Diams Expert Answers

1. Why choose a GIA-certified diamond rather than an uncertified diamond?

Choosing a diamond also means choosing how it is understood.

A certificate from the Gemological Institute of America (GIA) provides an independent and internationally recognized assessment of a diamond’s essential characteristics: carat weight, color, clarity and cut quality.

Founded in 1931, GIA is among the oldest and most respected gemological laboratories in the world.

It is widely regarded as the benchmark grading authority for diamonds.

It allows you to understand precisely what you are acquiring, compare diamonds on consistent grounds, and place your choice within a framework of lasting transparency.

At DIAMS, GIA certification stems from a commitment to transparency.

An important choice deserves reliable information.

Understanding a certificate also helps reveal the nuances between two diamonds whose appearance may seem similar, yet whose rarity, value or character may differ.

A certificate does not create a diamond’s beauty.

It helps recognize it.

2. How should the 4Cs be read when choosing a diamond?

The 4Cs, carat, color, clarity and cut quality are not isolated criteria.

They are understood through their balance.

Carat gives presence.

Color and clarity speak to rarity.

Cut quality influences the way a diamond returns light.

Understanding the 4Cs does not mean systematically pursuing the highest grades.

It means understanding which criteria matter most for your project.

For a deeper understanding, we have dedicated a complete guide to the 4Cs of diamond quality.

3. How should one balance carat, color and clarity?

There is no universal hierarchy.

There is an equilibrium.

Some may favor greater presence by choosing a higher carat weight.

Others may prefer to move upward in color or clarity.

What matters is understanding what each choice brings.

At comparable grades, visual differences may sometimes be subtler than the differences in rarity they represent.

This is why the decision is not merely technical.

It is also personal.

The best diamond is not always the highest-graded one.

It is often the one whose balance feels right.

And within that balance, cut quality remains a major criterion.

4. Why can two diamonds have very different prices?

Two diamonds that appear visually similar can sometimes show significant differences in price.

This reflects the criteria that determine both value and rarity.

The first is carat weight.

As weight increases, rarity grows non-linearly, which strongly influences value.

Then come color and clarity.

Differences that may appear subtle to the eye can represent meaningful distinctions in gemological grading.

Cut quality also plays a role.

This is where the hand of man enters.

Beyond the material given by nature, proportions, symmetry and polish influence how a diamond returns light.

Price therefore does not reflect visible brilliance alone.

It expresses a combination of natural rarity and human craftsmanship.

Understanding this helps clarify what one is truly choosing.

5. How are diamonds selected at DIAMS?

Diamonds offered by DIAMS are selected according to gemological criteria designed to remain coherent and transparent.

Each stone is accompanied by a GIA certificate.

We propose qualities defined for each carat weight in order to preserve a thoughtful balance between rarity, beauty and budget.

Cut quality ranges from Excellent to Very Good, with close attention paid to Polish and Symmetry.

These nuances can be subtle, yet they contribute to a diamond’s character.

We also favor diamonds with no fluorescence.

Beyond the grades themselves, what matters is overall coherence.

It is this coherence that guides our selection.

6. What diamond size should you choose?

This question calls less for a rule than for a sense of rightness.

The right carat is not necessarily the largest one.

It is the one that corresponds to the gesture, the style desired, and the story it accompanies.

A half-carat can carry great intensity.

A one-carat diamond expresses a different presence.

The choice cannot be measured by visible dimensions alone.

More than brilliance, it is the promise it carries that makes a solitaire an enduring jewel.

Choosing according to one’s means is not a compromise.

It is often a form of rightness.

7. What difference does the choice of metal make: white gold, yellow gold, rose gold or platinum?

The metal does not merely change the color of a setting.

It changes the way a diamond is perceived.

18k white gold offers a classic, luminous expression.

18k yellow gold creates a warmer contrast.

18k rose gold brings a softer tone.

Platinum 950 has a denser presence, almost mineral in character.

None is inherently superior.

The choice depends on the style sought, complexion, and sometimes a more intimate sensibility.

The solitaire remains the same.

Yet its character takes on different nuances.

8. Why does the solitaire remain a symbol of commitment?

The solitaire has endured through time without losing its meaning.

One stone.

One presence.

One commitment.

Its symbolic force depends neither on carat weight nor on the degree of rarity of the diamond.

It resides in the gesture it represents.

More than brilliance, it is the promise it carries that makes a solitaire an enduring jewel.

That is why a half-carat chosen with justness can carry as much emotion as a larger stone.

A solitaire is not a display.

It is often an intention made visible.

In a world where many objects are replaced, some jewels are passed on.

The solitaire belongs to that rare category.

It unites matter, memory and promise.

9. How should a solitaire be cleaned and cared for?

A solitaire is often worn every day.

Simple, regular care is generally enough to preserve its brilliance.

Gentle cleaning with warm water, mild soap and a soft brush (Toothbrush) helps remove deposits that can soften a diamond’s light.

Beyond cleaning, we recommend having the setting checked periodically.

Caring for a solitaire is not a constraint.

It is a form of attention given to the jewel.

10. Can a ring size be adjusted later?

Yes, in most cases, resizing is possible.

It is part of the natural life of a jewel.

When properly executed, a size adjustment preserves both the proportions and comfort of the ring.

At DIAMS, this possibility forms part of the natural accompaniment of a solitaire.

11. What should I do if a diamond seems loose?

If a stone appears to move, even very slightly, it is best to stop wearing the ring and bring it to us for inspection.

A simple preventive re-tightening of the setting is often sufficient.

It is precisely this kind of attention that allows a jewel to pass through time with serenity.

12. What services accompany your DIAMS jewel over time?

A jewelry creation does not end when it is delivered.

It is part of a longer continuity.

Resizing, inspections, care, re-tightening of the setting when necessary, and personalized guidance — these services are part of a jewel’s life.

That continuity forms part of our conception of service.

13. How does DIAMS ensure the ethical origin of its diamonds?

In accordance with the Kimberley Process and United Nations resolutions, diamonds offered by DIAMS come from legitimate sources that do not contribute to the financing of armed conflicts.

This commitment is supported by written guarantees provided by our suppliers.

A diamond’s origin is part of its integrity.

This ethical dimension is not an added consideration.

It forms part of the trust a diamond destined to endure should carry.
