Carats / Diamond weight
Information about the relation between the weight and the diameter of a diamond
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).

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
Polish describes the finish of the diamond's surface. After the diamond is cut, each facet must be polished. This process can leave scratches or marks on the surface. If a diamond has no scratches or very minor scratches, the polish is high level. Scratches, lines, burn marks created by excessive heat, or rough sheathing can lower a diamond's polish rating. Polish is rated as Excellent (EX), Very Good (VG), Good (G), Fair (F) or Poor (P). The better the polishing, the more it allows the transmission of light through the different facets of the diamond. We recommend that you choose an Excellent (EX) or Very Good (VG) quality polish to ensure the best finish and shine.
Diamond Symmetry
Symmetry describes the symmetrical accuracy of the diamond facets in terms of dimensions and angles, as well as the centering of the table and the centering of the diamond breech tip. The more precise the symmetry, the better the cut of the diamond. A higher level of symmetry creates optimal shine and scintillation. If the facets are misaligned, the diamond can reflect light poorly. Symmetry is rated as Excellent (EX), Very Good (VG), Good (G), Fair (F) or Poor (P). We recommend that you choose a diamond with a symmetry score equal to Excellent (EX) or Very Good (VG) to maximize 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.
