The quality of a diamond is determined by 4 main criteria called the "4Cs": Carat (weight of the diamond), Colour (degrees of whiteness), Clarity (degrees of purity) and Cut (quality of the cut). Carat weight is the most important factor influencing the price of a diamond. However, we recommend that you consider each diamond as a whole according to its 4 quality criteria. In our diamond price catalog, place the cursors price, carat, color, clarity, cut and choice of certificate of authenticity according to your research in order to obtain a first selection of stones corresponding to your expectations. An additional filter allows you to choose among our 4 selections: perfection offer, choice of balance, offer of the moment or diamond dealer's favorite.

The importance of the purity criterion increases with the weight of the diamond. Indeed, if it is difficult to see an inclusion on a 0.30 carat diamond with the naked eye, it becomes much easier to see on a 1 carat diamond. The larger your diamond, the more demanding you are on this criterion.
That the term color does not deceive you. There are white diamonds and colored diamonds (yellow, pink, blue ...). For white diamonds, the color note, between D and Z, refers to shades of whites: white goes from colorless (D) to yellow (from I).
We recommend diamonds with a white color between D (exceptional white +) and H (white) because the whiteness of the diamond increases its brilliance.

What is the difference between a GIA, HRD and IGI certificate?
In our diamond catalog we only offer diamonds with a certificate of authenticity and quality issued by one of the 3 most prestigious and internationally recognized laboratories: GIA, HRD and IGI.
The American laboratory GIA is the most famous and strictest in terms of grading stones. GIA is also the first world laboratory of reference because the American market represents 50% of the world demand. HRD and IGI are the two other world-renowned historical laboratories, both European and located in Antwerp (Belgium), the world diamond center.
Other laboratories such as AIG, EGL... should be avoided because they are not recognized worldwide, they are much less strict in their grading and are said to be of convenience.
Unlike synthetic diamonds produced artificially in laboratories, natural diamonds were created billions of years ago 150 km below the earth. A true miracle of nature and eternal, the diamond carries the message of a rare and unique story and the symbol of a true and lasting love, charged with emotion, unlike the synthetic diamond.
There are multiple shapes of cut diamonds. We distinguish the cut of the round brilliant diamond the diamonds known as "fancy", like the diamond of princess shape, emerald shape, oval shape, pear shape, cushion shape and many others. The round brilliant diamond is the one that shines the most and that we sell in great majority. However, simply ask us which "fancy" diamond you are looking for. We will do our best to offer you the unique diamond by its shape, size, color, clarity, type of inclusions and weight that you want.
