Carats / Diamond weight
Move the diamond weight slider and view the rendering on a hand, chest or ears.
On the photo above, you can view different diamond diameters on a hand, by moving the slider. The fingertip of this hand is a size 53 (a measure quite common and which corresponds to an inner diameter of 1.68cm for the ring). The diameter of a diamond is proportional to its weight in carat (ct). The higher the weight, the larger the diamond. Carat is another unit of measurement of weight (1 carat = 0.2 gram).
On the photo above, you can view different diamond diameters on a woman's neck. The diameter of a diamond is proportional to its weight in carat (ct). The higher the weight, the larger the diamond. Carat is another unit of measurement of weight (1 carat = 0.2 gram).

Diamond colours
Our recommandation
We recommend diamonds with a white hue between D (exceptional white+) and H (white) because the whiteness of the diamond increases its brilliance. From color grade I and J (slightly tinted) onwards, diamonds are slightly yellow-tinted: avoid on white gold and acceptable on yellow gold.
D-EExceptional white
F-GExtra white
HWhite
I-JSlightly tinted
K-MTinted white
N-ZVery tinted
Diamond clarity
Our recommandation
We recommend that you avoid choosing a Pique diamond, because inclusions are easily seen with the naked eye, alter the brilliance and can even weaken the stone. The clarities included in VS and SI1 are the most recommended , unless you have the budget to let yourself be tempted by IF or VVS clarities, which sign the diamond in its highest dimension: that of purity.

VVSVery very small inclusion(s)
VSVery small inclusion(s)

Diamond cut
When a diamond is well cut, light reflects from one facet to the other, making the most of the diamond's high refractive property. A less well-cut diamond lets some of the light escape.
Our recommandation
We advise you to choose a diamond with a quality rating equal to Excellent (EX) or Very Good (VG) to maximize the refraction of light and therefore the diamond brilliance.

Most recognized certificates: GIA, HRD and IGI
We only offer natural diamonds accompanied by a certificate of authenticity and quality issued by one of the 3 most prestigious and world-renowned laboratories: GIA, HRD and IGI. The certificate number is engraved on the girdle (circumference) of all our HRD, IGI and GIA certified diamonds.
Laser engraving
The three major diamond certification laboratories HRD, IGI and GIA laser engrave the certificate number on the girdle (circumference) of the diamond. The certificate number is therefore engraved on all our HRD, IGI and GIA certified diamonds. This is a proof of the good match of the diamond and its certificate. The inscription is very small (to preserve the purity of the stone) and very difficult to read with the magnifying glass 10X.
If you order only the diamond (without the jewel), it will be delivered under seal in a rigid plastic pouch (see photo below) for diamonds certified by HRD or by IGI. For GIA diamonds, the seal must be specifically requested in the comments field during the ordering process.
Diamond Fluorescence
Fluorescence is a luminous effect that some diamonds exhibit when exposed to ultraviolet light. They show visible light, usually blue.
Our recommandation
Since fluorescence may in some cases give a milky diamond appearance, prefer a diamond without fluorescence ("None" or "Nil")

Diamond Polishing
When cutting the diamond, each facet must be polished. If a diamond has no scratches or very minor scratches on the surface, the polish is high. The better the polishing, the more it allows the transmission of light through the different facets of the diamond.
Our recommandation
We recommend choosing a polish rated Excellent (EX) or Very Good (VG) to ensure the best finish and shine.

Diamond Symmetry
Symmetry describes the symmetrical accuracy of the facets of the diamond in terms of dimensions and angles, as well as the centering of the table and the centering of the breech point of the diamond. A higher level of symmetry creates optimal shine and scintillation.
Our recommandation
We advise you to choose a diamond with a symmetry rating equal to Excellent (EX) or Very Good (VG) to maximize the sparkle.

In partnership with Everledger, the world's leading blockchain technology company, we are setting the standards for a new way of working in the diamond industry and continuing to drive transparency and accountability for our industry players. State-of-the-art blockchain-based technology has been integrated into our supply chain to transparently and securely track the origin of stones and provide greater assurance to our customers about the provenance of our diamonds.
Thanks to the partnership with the Blockchain Everledger technology, our website i-diamants.com now allows you to know where your diamond comes from. On our diamond catalog, when you select the “Traceable via the Everledger blockchain” filter, you can choose a diamond that has been traced from its country of origin via the Everledger blockchain. This transparency on the origin of the diamonds allows you to be sure of the following 2 fundamental points:
- Your diamond comes from countries at peace and signatories of the Kimberley Process
- The chain of subcontractors is Responsible Jewelery Council certified, the human and environmental criteria are evaluated, audited and collected regularly (even if these points obviously require continuous improvement).
Diamond origins
For these diamonds, the country of origin of the diamond is mentioned on the GIA certificate. To be able to trace a diamond from rough to cut, GIA collects and analyzes the physical measurements, spectroscopic data and imagery of the rough diamond before it is cut. An identification number is assigned to the rough diamond. The GIA later uses this data to scientifically match the cut diamond to the original rough diamond from which it came.
