Selections

We recommend the following 5 selections

To help you choose, we recommend 5 categories of diamonds that correspond to different purposes: Volume (maximizing weight), Balance (compromise weight and quality), Perfection (maximizing quality), Cut of heart (the i-diamonds recommendation), Promotion (one-time price offer).

Volume effectmaximize the weight of the diamond relative to its price, I-J color and SI1-SI2 clarity

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).

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.

IFPure

VVSVery very small inclusion(s)

VSVery small inclusion(s)

SISmall inclusion(s)

IF : Pure

No inclusion inside the stone

VVS1 VVS2 : Very very small inclusion(s)

VS1 VS2 : Very small inclusion(s)

SI1 SI2 : Small inclusion(s)

P1 P2 P3 : Included

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

Always ask to see the certificate before purchasing a certified diamond. For all of our certified diamonds, we display a link (GIA, HRD or IGI) that you can click to view the diamond’s full certificate.

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.

VGVery Good

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.
