Two diamonds can share the same carat weight.
The same colour grade.
The same clarity grade.
Even the same shape.
On paper, they may appear almost identical.
Place them beside one another, however, and the difference can be immediate.
One holds the eye.
The other simply meets the specification.
One seems alive with light.
The other has all the correct numbers and somehow leaves you unmoved.
This is where diamond grading ends and diamond selection begins.
A grading report is essential. It gives structure to understanding a diamond. It records measurable and observable characteristics, establishes important quality information and allows stones to be compared with greater transparency.
But a report cannot experience beauty.
It cannot decide whether an oval possesses graceful proportions.
It cannot feel whether a pear shape has character.
It cannot determine whether an emerald cut has that elusive combination of openness, balance and quiet sophistication.
And it cannot know whether a particular diamond belongs in a particular jewel.
That requires another form of judgement.
At Galassia, selecting a diamond is not simply a matter of finding a stone that reaches a predetermined set of grades.
It is an act of editing.
Of comparing.
Of rejecting.
Of looking beyond what is acceptable towards what feels exceptional.
Because the diamond does not merely enter the design.
Very often, it defines it.
A Diamond Is More Than Its Certificate
Modern diamond grading has transformed the way diamonds are understood.
Carat.
Colour.
Clarity.
Cut.
Measurements.
Polish.
Symmetry.
Fluorescence.
And depending on the diamond and laboratory report, additional information concerning its proportions, characteristics and origin.
These details matter.
Deeply.
But a diamond grading report should be understood for what it is:
a description, not a portrait.
Consider two people of identical height.
That measurement may be perfectly accurate.
It tells you almost nothing about how similar those two people actually look.
Diamond specifications can work in much the same way.
Two 1.50-carat oval diamonds can have very different length-to-width relationships.
Two diamonds of the same colour grade may present differently depending on shape, cutting style and setting.
Two stones with the same clarity grade may contain entirely different types of inclusions in entirely different locations.
Two round diamonds carrying the same cut grade can still possess subtly different visual personalities.
The report gives us information.
The diamond gives us the final answer.
Selection Begins With the Purpose of the Jewel
There is no universally perfect diamond.
There is only the right diamond for the right creation.
Before selecting a stone, one must understand what it is being asked to do.
Is it the centre of an engagement ring?
One half of a Toi et Moi composition?
A pair that must be carefully matched for earrings?
A diamond intended for a pendant viewed from greater distance?
Part of a highly geometric design?
A stone that needs to sit low?
A diamond selected around a client's preference for elongated proportions?
A stone whose colour is intentionally part of the design?
This changes the selection process completely.
A diamond does not exist independently from the jewel around it.
Its shape affects the architecture.
Its proportions influence the setting.
Its dimensions affect visual scale.
Its character influences what should surround it—and sometimes what should not.
At Galassia, diamond selection and jewellery design belong to the same conversation.
We do not believe the stone should be selected in isolation and the design forced around it afterwards.
The diamond and the jewel should resolve one another.
The 4Cs Are the Beginning
The traditional framework of the 4Cs—cut, colour, clarity and carat weight—remains fundamental to understanding diamond quality.
But understanding them well means going beyond the letters and numbers.
A larger carat number does not automatically create a more beautiful diamond.
A higher clarity grade does not necessarily create a stone that appears more compelling to the unaided eye.
A higher colour grade may not always be the most intelligent place to allocate a client's priorities.
And cut cannot simply be reduced to the outline of the stone.
Diamond selection requires understanding what each characteristic contributes—and where it matters most.
The objective is not to pursue grades for their own sake.
The objective is to select beauty intelligently.
Cut: Where Light Becomes Character
Of all the familiar diamond characteristics, cut has an extraordinary influence on visual appearance.
A polished diamond works through geometry.
Its facets receive light.
Redirect it.
Return it.
Break it into flashes of spectral colour.
Create brightness.
Contrast.
Movement.
Scintillation.
Change the proportions and that relationship with light changes.
This is why two diamonds of similar weight and quality specifications can feel remarkably different when viewed.
A beautifully cut diamond does not merely sparkle more.
It has rhythm.
Areas of brightness and contrast interact as the stone, viewer or light moves.
The eye receives changing flashes rather than a static field of white.
There is life inside the stone.
When Galassia considers a diamond, we therefore look beyond whether the relevant cut information reaches a satisfactory grade.
We consider what the diamond actually does.
Because ultimately, cut is experienced through light—not through a line on a report.
Shape Is Not the Same as Cut
The words are often confused.
When someone asks for an oval cut, pear cut or emerald cut diamond, they are usually speaking about shape or cutting style.
But evaluating how well that shape has been executed requires a deeper examination.
Round brilliant diamonds benefit from established cut-grading systems.
Fancy shapes are more nuanced.
Oval.
Pear.
Marquise.
Cushion.
Emerald.
Radiant.
Heart.
Princess.
Each introduces different questions.
There is no single proportion that makes every example beautiful.
This makes human observation particularly important.
With fancy-shaped diamonds, selection becomes an exercise in balance.
Not only:
What shape is it?
But:
How beautifully does this particular diamond express that shape?
An Oval Should Have a Point of View
An oval diamond is not simply a stretched round.
Its length matters.
Its width matters.
Its shoulders matter.
Its curvature matters.
So does the relationship between all of them.
Some ovals are soft and full.
Others are dramatically elongated.
Some feel classical.
Others feel contemporary.
Neither approach is automatically superior.
The question is whether the proportions feel intentional.
The famous bow-tie effect also enters the conversation.
Many elongated brilliant-cut shapes can display an area of contrast through the centre that resembles a bow tie.
Some degree of contrast can be part of the diamond's character.
But when it becomes too dark or visually dominant, it may interrupt the stone rather than enrich it.
A report cannot fully communicate that experience.
The eye must decide.
At Galassia, we do not select an oval because the spreadsheet says “oval.”
We select the individual oval.
A Pear Diamond Must Find Balance Between Two Opposites
A pear-shaped diamond combines two completely different gestures.
A curve.
And a point.
That tension is what gives the shape its character.
But it also makes proportion exceptionally important.
Too broad and the stone may lose elegance.
Too narrow and it may appear stretched.
The shoulders can feel graceful or awkward.
The point can feel naturally integrated or visually abrupt.
Symmetry becomes particularly visible.
Then comes personality.
Some pear diamonds feel romantic.
Some architectural.
Some delicate.
Some dramatic.
When used in a bespoke composition or paired with another shape, the precise personality of the pear can influence the entire design.
A certificate records a pear-shaped diamond.
Selection determines which pear.
Emerald Cuts Ask a Different Question
Brilliant-cut diamonds often seduce through movement.
Emerald cuts do something else.
They reveal.
Broad, linear facets create flashes of light rather than the rapid scintillation associated with many brilliant cuts.
The eye is invited into the stone.
This makes proportion, clarity and transparency particularly important.
An emerald cut can feel calm.
Architectural.
Almost impossibly refined.
But its apparent simplicity leaves little room for visual disorder.
The hall-of-mirrors effect associated with a strong emerald cut depends on an elegant relationship between facets, contrast and openness.
Here, again, the grade alone is not enough.
A great emerald cut should have composure.
One sees the structure immediately.
And because so much of the interior is visually accessible, the stone asks to be judged with particular honesty.
There is nowhere for an uninspired diamond to hide.
Colour Is Experienced, Not Merely Graded
In colourless to near-colourless diamonds, laboratory colour grades help communicate the amount of body colour observed under controlled conditions.
Those grades are extremely useful.
But jewellery is not worn under laboratory grading conditions.
A diamond is viewed face-up.
In changing light.
Against skin.
Beside metal.
Surrounded by other stones.
White gold can create one visual relationship.
Yellow gold another.
Rose gold another.
The cutting style of the diamond can also affect how colour is perceived in normal viewing.
This does not make grading less important.
It makes design more important.
Selecting a diamond intelligently means understanding both its laboratory grade and how that grade will participate in the finished jewel.
The question is never simply:
How high is the colour?
It is:
How beautiful is the relationship between this diamond, this design and this metal?
Fancy Colour Diamonds Reverse the Conversation
When colour becomes intentional, the philosophy changes entirely.
Yellow.
Pink.
Blue.
And other coloured diamonds are not necessarily judged according to the same desire to minimise visible colour.
Colour becomes the event.
Its strength.
Distribution.
Tone.
Saturation.
And the way the stone has been cut to express that colour become part of its identity.
At Galassia, coloured diamonds can become extraordinary design instruments precisely because they refuse neutrality.
They introduce emotion immediately.
A vivid colour beside white diamonds creates contrast.
Two colours together create dialogue.
A coloured centre stone can turn an otherwise restrained composition into something unforgettable.
The challenge is no longer hiding colour.
It is honouring it.
Clarity Should Be Understood, Not Worshipped
Clarity is one of the most misunderstood areas of diamond buying.
Diamonds form with internal characteristics and may also possess surface characteristics created during their journey from rough crystal to polished gemstone.
Laboratories assess these according to established grading standards.
The resulting clarity grade is useful.
But the letters themselves can become dangerously seductive.
It is easy to assume that a technically higher clarity grade must always create a visibly more beautiful diamond.
That is not necessarily how selection works.
The nature of an inclusion matters.
Its location matters.
Its size matters.
Its visibility matters.
Its effect on transparency can matter.
And the type of diamond matters.
An inclusion hidden near the edge of one stone may have a very different visual consequence from a similar characteristic positioned beneath the centre of another.
For Galassia, clarity is therefore not simply a race towards the highest available abbreviation.
We ask what the characteristics actually mean for the stone.
A grade is information.
Judgement is interpretation.
Transparency: The Quality People Often Feel Before They Can Name It
Some diamonds appear crisp.
Others seem slightly sleepy.
A stone may have respectable specifications and yet fail to possess the visual openness expected from it.
This is why transparency deserves attention.
Not every factor influencing transparency is communicated through a single headline grade.
Certain clarity characteristics, their density and their interaction with light can influence how open or hazy a diamond appears.
This distinction can be subtle.
But once noticed, it becomes difficult to ignore.
A lively diamond has a certain immediacy.
Light appears to move through it cleanly.
The facets communicate clearly.
Nothing seems to stand between the viewer and the stone.
That quality is difficult to reduce to a single number.
It is also one of the reasons we believe diamonds should be selected, not merely ordered.
Carat Is Weight, Not Visual Size
Carat is perhaps the most famous diamond measurement.
It is also one of the easiest to misunderstand.
A carat is a unit of weight.
It does not directly tell you how large a diamond will appear from above.
Two diamonds of equal weight may face up differently because their proportions distribute that weight differently.
A deep stone may carry more of its mass vertically.
Another may spread more of that weight across its visible diameter or dimensions.
Shape also changes perception dramatically.
A 1.50-carat round, oval, emerald cut and pear do not present themselves identically on the hand.
This is why Galassia considers dimensions alongside weight.
We are not selecting a number to print on an invoice.
We are selecting the visual scale of the finished jewel.
Sometimes the most compelling diamond is not the one with the largest carat figure.
It is the one whose weight has been used beautifully.
Millimetres Matter
Fine jewellery operates in a world where fractions can transform perception.
A few tenths of a millimetre may alter how elongated a diamond appears.
A small change in width may affect how two stones sit beside one another.
Dimensions influence how a centre stone relates to a band.
They affect halo proportions.
Side-stone relationships.
Spacing.
Setting architecture.
Coverage across the finger.
Balance in earrings.
Even the difference between subtle and dramatic.
This is why experienced diamond selection is often surprisingly physical.
One learns to think in millimetres.
Not because romance should be reduced to mathematics.
But because mathematics can help protect the romance from poor proportion.
Symmetry Is More Than a Word on the Report
Symmetry concerns the precision and alignment of a diamond's facets and overall cutting.
Laboratory symmetry grades provide important information.
But certain shapes also require visual symmetry to be considered in a broader sense.
Look at a pear.
Are the shoulders balanced?
Look at a heart.
Do the lobes relate beautifully?
Look at a marquise.
Does the shape feel centred from tip to tip?
Look at an oval.
Does one side feel fuller than the other?
The human eye is extraordinarily sensitive to imbalance, particularly in shapes built around a strong central axis.
A tiny irregularity may never appear consciously as a defect.
The viewer may simply feel that something is wrong.
Great selection catches that feeling before the diamond ever reaches a setting.
Polish Matters Because Light Encounters the Surface First
A diamond may possess extraordinary internal architecture, but light must still meet its polished surfaces.
Polish refers to the quality of finish on those surfaces.
It is another example of something that sounds purely technical until one remembers what a diamond is designed to do.
Interact with light.
Every detail that influences that interaction deserves attention.
In fine jewellery, excellence is rarely created by one dramatic decision.
It is accumulated through dozens of smaller ones.
Polish is one of them.
Fluorescence Is Not Automatically Good or Bad
Few diamond characteristics produce as much unnecessary fear as fluorescence.
Fluorescence refers to the visible light some diamonds emit when exposed to ultraviolet radiation.
Its presence and intensity can be noted on a laboratory report.
But fluorescence should not automatically be treated as a defect.
In many diamonds, its effect under normal viewing conditions may be minimal or unnoticeable.
In certain cases it can influence visual appearance, making examination of the actual stone important.
The intelligent approach is therefore not:
Fluorescence equals bad.
Nor:
Fluorescence does not matter.
It is:
What does fluorescence do in this particular diamond?
That question reflects the philosophy behind good selection generally.
Avoid assumptions.
Look at the stone.
Matching Diamonds Is a Discipline of Its Own
Selecting one beautiful diamond can be demanding.
Selecting two beautiful diamonds that also belong together can be harder.
For earrings, Toi et Moi designs, side stones and multi-stone compositions, individual quality is only the beginning.
The diamonds must communicate.
Two round stones may need compatible diameter, colour, brightness and overall character.
A pair of ovals must not only share similar dimensions; their outlines should feel related.
Two emerald cuts may technically match in size while displaying noticeably different facet personalities.
In a Toi et Moi ring, the challenge is more interesting still.
The stones may intentionally be different.
Pear and round.
Emerald and oval.
White and coloured.
Yet difference must still create harmony.
Matching does not always mean making stones identical.
Sometimes it means finding two diamonds whose differences make sense together.
That is jewellery design through selection.
The Setting Can Change Which Diamond Is Right
Imagine selecting a diamond without knowing how it will be worn.
Something essential is missing.
A bezel setting interacts differently with a stone than fine prongs.
A halo changes perceived scale.
A low-profile ring introduces different structural considerations from a dramatic elevated setting.
Yellow metal can alter the visual relationship with diamond colour.
A three-stone composition requires the centre and side stones to establish hierarchy.
A Toi et Moi design requires dialogue.
An engagement ring worn every day must consider not only beauty, but durability and lifestyle.
This is why Galassia's fully integrated atelier approach matters.
Design.
CAD.
Diamond selection.
Setting.
Polishing.
Finishing.
These are not independent departments attempting to solve unrelated problems.
They are different stages of one object.
When the entire creation remains within one continuous process, the diamond can be evaluated in the context of what it is actually going to become.
That is a profound advantage.
Natural and Lab-Grown Diamonds Still Require Selection
Growth origin changes the story of a diamond.
It does not remove the need for judgement.
Whether a client chooses a natural diamond or a laboratory-grown diamond, individual stones can still differ in cut, colour, clarity, proportions and visual character.
There can still be stronger stones and weaker stones.
More elegant shapes and less elegant shapes.
Better matches and poorer matches.
Diamonds that work for one design and diamonds that do not.
The idea that every laboratory-grown diamond is visually interchangeable is no more useful than assuming every natural diamond of the same grade is identical.
A specification creates a category.
Selection chooses the individual.
At Galassia, the principle remains the same:
The stone must serve the jewel.
Certification Creates Confidence. Selection Creates Character.
Certification has an essential role in modern fine jewellery.
It creates clarity.
It records important characteristics.
It supports transparency.
It gives the owner documentation connected with the diamond or completed jewel.
Galassia supports its jewellery with IGI certification and relevant documentation, helping clients understand specifications and quality information associated with their pieces.
But certification and curation perform different jobs.
Certification tells us what has been independently assessed.
Selection asks whether we want to work with that stone.
The two should complement one another.
Never compete.
A maison confident in its diamonds should welcome documentation.
But it should also possess the expertise to look beyond it.
Sometimes the Best Decision Is to Reject the Diamond
Luxury is often discussed through what is chosen.
Far less is said about what is refused.
Yet rejection is one of the most important parts of selection.
A diamond may technically meet the requested colour.
Reject it.
The proportions feel wrong.
Another may achieve the desired clarity.
Reject it.
The visual character is weak.
Another may offer impressive carat weight.
Reject it.
Too much of that weight is hidden in depth.
Another may look attractive alone.
Reject it.
It does not balance with its matching stone.
This is where curation earns meaning.
Selection is valuable precisely because everything is not selected.
At Galassia, the standard is not:
Can this diamond be used?
The more important question is:
Should it be?
Those are very different questions.
There Is No Algorithm for Taste
Technology has made diamond comparison extraordinarily efficient.
Databases can filter thousands of stones by:
Carat.
Colour.
Clarity.
Shape.
Measurements.
Ratios.
Certification.
Price.
Other specifications.
That is useful.
Necessary, even.
But eventually, a filtered list has to become a decision.
And this is where taste enters.
A computer can identify three oval diamonds with near-identical measurements.
It cannot reliably tell us which one possesses the most graceful outline for the piece being designed.
It can sort emerald cuts by table percentage.
It cannot experience the calmness of a beautifully resolved step-cut pattern.
It can find matching weights.
It cannot understand the emotional balance of two different diamond shapes in a bespoke composition.
Technology can narrow the field.
The human eye still edits it.
Selection Is Where Experience Becomes Invisible
When expertise is used well, the client may never see the complexity behind it.
They see one diamond.
Perhaps two.
Perhaps a small considered selection.
They do not necessarily see every stone that was rejected first.
Every proportion compared.
Every inclusion considered.
Every measurement checked.
Every pair that almost matched.
Every stone that looked impressive on paper and disappointing in person.
This invisibility is part of service.
Luxury is not presenting the client with every possible option.
Sometimes luxury is doing enough work that only the right options remain.
At Galassia, this is how we think about curation.
The complexity belongs behind the scenes.
Clarity belongs in front of the client.
A Diamond Should Be Beautiful in More Than One Kind of Light
Jewellery lives everywhere.
Morning light.
Office light.
Restaurant light.
Direct sunlight.
Soft evening illumination.
The controlled environment in which a diamond is graded is necessary for consistency.
But the wearer will not spend their life inside a grading laboratory.
A diamond should therefore be understood as a moving object in changing conditions.
Does it maintain life as the lighting becomes softer?
How does contrast behave?
What happens when the stone moves?
Are flashes broad or rapid?
Does the shape remain clearly defined?
Does a dark area become distracting?
Selection becomes richer when the diamond is not treated like a static image.
Diamonds are optical objects.
They should move.
So should the person judging them.
The Most Expensive Diamond Is Not Automatically the Best Choice
Fine jewellery requires discernment partly because budgets are finite.
Even at the highest levels, every choice has an opportunity cost.
Increase carat significantly and another characteristic may need reconsideration.
Pursue extremely high clarity beyond what has visible relevance and the client may be paying for rarity that does little to change the appearance of the finished jewel.
Insist upon a particular colour grade without considering metal and design and one may overlook a diamond that performs beautifully in context.
Intelligent selection is not about spending less.
Nor is it about spending more.
It is about understanding where quality becomes visible.
That is one of the responsibilities of a fine jewellery maison.
To translate technical information into meaningful decisions.
The Diamond Must Survive the First Impression
Many diamonds are impressive for several seconds.
Size can impress immediately.
A dramatic shape can impress immediately.
High specifications can impress intellectually.
But enduring jewellery asks for something more.
The diamond must remain compelling after familiarity arrives.
After the first photograph.
After the proposal.
After the first dinner.
After the novelty of ownership disappears.
Eventually, the wearer stops seeing a grading report.
They simply see their ring.
Their pendant.
Their earrings.
Their diamond.
This is why we believe visual character matters.
A future heirloom has to survive more than inspection.
It has to survive intimacy.
At Galassia, Diamonds Are Selected for the Jewel They Will Become
Galassia is built around an in-house approach to fine jewellery.
The creation begins with design and continues through CAD development, diamond selection, setting, polishing and final finishing within our atelier process.
This continuity changes how we think about diamonds.
We are not purchasing anonymous specifications that exist separately from the jewellery.
We are considering material for an object we intend to create.
That means asking more.
Does this diamond possess the right visual scale?
Does its personality strengthen the design?
Do the proportions make sense within the setting?
Is the stone worthy of the craftsmanship that will surround it?
Does it contribute to refinement rather than simply expense?
Would we still choose it if the grading report were temporarily turned face down?
That final question matters.
Because numbers should support beauty.
They should never be asked to substitute for it.
From Rarity to Relevance
Rarity is one of the foundations of luxury.
But rarity alone does not create significance.
A rare object can still be poorly chosen.
A large diamond can still be inelegant.
An extraordinary grade can still be irrelevant to the final design.
At Galassia, rarity becomes interesting when it has purpose.
A remarkable pair of stones.
An unusual shape.
An exceptional coloured diamond.
A beautifully proportioned centre stone.
A diamond whose character unlocks an entirely new design.
That is when rarity becomes more than a statistic.
It becomes creative material.
The Diamond Should Not Overpower the Design
In fine jewellery, there can be a temptation to allow the stone's specifications to become the entire story.
But a great jewel is a composition.
Diamond.
Metal.
Setting.
Proportion.
Negative space.
Movement.
Craftsmanship.
The relationship between them matters.
Sometimes the correct design becomes almost invisible around an extraordinary diamond.
Sometimes metal architecture gives the stone context.
Sometimes multiple diamonds create the effect collectively.
Sometimes an unexpected contrast is what makes the entire piece memorable.
This is why Galassia does not view diamond selection as an isolated purchasing exercise.
Selection is design.
The stone has to know its role.
A Future Heirloom Begins With Standards Nobody Else May Ever See
Years after a jewel is created, nobody may remember its original shortlist.
Nobody may know that several diamonds were rejected.
They may never see the CAD revisions.
They may not know why one setting angle changed.
Why one pair of stones was reconsidered.
Why a fraction of metal was removed.
Why a different centre diamond was ultimately chosen.
They will only know the finished object.
That is exactly how it should be.
At Galassia, true luxury begins before the jewel is worn.
It exists in decisions made when nobody is watching.
In standards the eventual owner may never need to think about.
In the refusal to confuse acceptable with exceptional.
In the patience to continue looking.
Because a jewel created to transcend a season cannot begin with a stone chosen merely because it satisfies a filter.
It should begin with conviction.
How Do You Know When You Have Found the Right Diamond?
There is a point in diamond selection when comparison becomes surprisingly quiet.
You stop thinking about what the next stone might offer.
You stop moving repeatedly between reports.
You stop trying to rationalise one weakness against another.
The diamond simply makes sense.
Its proportions feel resolved.
Its light feels alive.
Its character suits the design.
Its specifications support what the eye already understands.
This does not mean expertise becomes irrelevant.
It means expertise has led to clarity.
The right diamond is not always the diamond with the most impressive combination of letters and numbers.
It is the one where nothing important feels compromised.
Frequently Asked Questions
How are diamonds selected for fine jewellery?
Diamonds are generally evaluated using laboratory grading information alongside direct assessment of their visual appearance. Factors can include carat weight, colour, clarity, cut quality, measurements, proportions, polish, symmetry, fluorescence, transparency, shape character and suitability for the intended jewellery design.
Are the 4Cs enough to choose a diamond?
The 4Cs provide an essential framework, but diamonds sharing similar grades can still differ visually. Shape proportions, inclusion placement, transparency, facet pattern, dimensions and overall character can influence how appealing a particular diamond appears.
Can two diamonds with the same grading specifications look different?
Yes. Grading categories contain ranges, and individual diamonds have unique proportions and characteristics. Two stones with similar headline grades may therefore differ in face-up size, outline, contrast, brightness, inclusion visibility and overall visual personality.
Is cut more important than carat?
There is no universal hierarchy because priorities differ between buyers and designs. However, cut has a major influence on how a diamond interacts with light, while carat measures weight rather than beauty. A thoughtfully selected diamond balances the characteristics that matter most for the intended jewel.
Does a higher clarity grade always mean a more beautiful diamond?
Not necessarily. Higher clarity grades indicate fewer or less significant clarity characteristics under established grading conditions, but visual beauty depends on many additional factors. The location and nature of inclusions, transparency, cut and overall appearance should also be considered.
Why do two diamonds of the same carat appear different in size?
Carat measures weight rather than face-up dimensions. Diamonds can distribute their weight differently depending on shape and proportions, meaning two stones of identical carat weight can have different visible measurements.
What is the bow-tie effect in oval and pear diamonds?
Bow tie refers to a pattern of contrast that can appear across the centre of certain elongated fancy-shaped diamonds, particularly ovals, pears and marquises. The visibility and severity vary by stone. Some contrast is normal, while a strong dark bow tie may become visually distracting.
Is diamond fluorescence bad?
Not inherently. Fluorescence describes a diamond's reaction to ultraviolet light. Its impact varies, and in many diamonds there is little noticeable effect under ordinary viewing conditions. The individual stone should be assessed rather than fluorescence being automatically treated as positive or negative.
How are diamonds matched for earrings?
Matching diamonds for earrings involves more than equal carat weight. Jewellers may compare dimensions, shape, colour, clarity, proportions and overall visual character so the stones appear harmonious when worn together.
How are diamonds selected for a Toi et Moi ring?
A Toi et Moi design may deliberately combine different shapes or colours, so selection focuses on visual relationship rather than identical matching. Scale, proportion, height, orientation, contrast and the personality of each diamond should create a balanced composition.
Are natural and lab-grown diamonds selected differently?
Both natural and lab-grown diamonds can be evaluated according to quality characteristics such as cut, colour, clarity, carat weight, proportions and visual appearance. Growth origin is an additional consideration, but careful individual stone selection remains important for both.
Why is diamond certification important?
Independent documentation provides structured information about a diamond's characteristics and supports transparency when comparing or purchasing stones. Certification should be considered alongside examination of the diamond's actual visual appearance.
Does Galassia provide diamond certification?
Galassia states that its jewellery is supported by IGI certification and relevant documentation, with grading and certificate information explained to clients where applicable.
The Certificate Ends Where Selection Begins
A diamond report can tell us a remarkable amount.
Its weight.
Its colour.
Its clarity.
Its measurements.
Its finish.
Its identifying characteristics.
These things deserve to be understood.
But eventually the report has said everything it can say.
Then somebody has to look at the diamond.
Really look.
Observe how it responds to light.
Understand its proportions.
Consider its character.
Imagine the setting.
Compare it with another.
Reject what is merely adequate.
And recognise when the correct stone has appeared.
That moment is not a measurement.
It is judgement.
At Galassia, diamond selection sits within the same continuous philosophy that guides our design, CAD development, setting, polishing and finishing.
Every decision serves the finished jewel.
Because we do not create jewellery simply for the moment it is purchased.
We create with the possibility that it will be worn deeply.
Remembered.
Kept.
Passed forward.
A future heirloom deserves more than a diamond that was correct on paper.
It deserves a diamond someone cared enough to choose.
