F.A.Q. Diamants

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.

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.

The diamond is undoubtedly a safe haven. However accidents of life sometimes force their owners to sell it. But most individuals do not know how to do it. In addition to the penalty that accompanies this sale, questions arise on the redemption diamond. What is the value of this jewel that I own?

The demand for diamonds is a crucial factor that affects their price in the market. Indeed, the demand is directly linked to the supply and to the balance of prices on the diamond market. If demand is high, prices go up, while if demand is low, prices go down. It is therefore important to understand how the demand for diamonds is influenced to understand price fluctuations in the market.

The quality of a diamond is a fundamental criterion for determining its price. Quality is measured based on four criteria: color, clarity, cut quality and carat weight. Color is rated on a scale from D (whitest color) to Z (most yellowish color). D, E and F color diamonds are considered to be the rarest and most beautiful, and are therefore the most expensive.

First of all, quality is a major factor in the price of diamonds. Quality is measured based on four criteria: color, clarity, cut quality and carat weight. The rarest and most beautiful diamonds are white in color, without visible inclusions and perfectly cut.

The weight of a diamond is measured in carats (ct), and it is an important factor to consider when buying a diamond. However, the weight of a diamond should not be confused with the quality of a diamond. The quality of a diamond is determined by factors such as color, clarity, and cut, which influence a diamond's brilliance, clarity, and symmetry.
