The diamond

“The diamond is eternal”


Everything you need to know about diamonds

Diamonds are classified, internationally, precisely according to 4 evaluation criteria (the 4Cs).
The most coveted and therefore the highest in budget combine the excellence of these 4 criteria: CUT (size), COLOR (color), CLARITY (purity) and CARAT (weight)



Purity (CLARITY) defines the degree of presence of inclusions in a diamond. This is determined by the number, type, and size of the inclusions under 10x magnification. The degree of purity is a key selection criterion because it has a significant impact on the price. The purer a stone is, the more valuable it is.



Color (COLOR) refers to the degree of colorlessness of a diamond. The degree of color (or lack thereof) has a significant impact on the value of the diamond. The rarest and highest budget diamonds are diamonds that show no color shading (D to H).

Conversely, tinted diamonds (usually yellow or brown) are more common. The Gemmological Institute of America (GIA) classifies diamonds from the letter D (Exceptional White) to the letter Z (tinted) to describe the color according to the scale below:



Refers to the shape, angles and proportions of a diamond. The size is based on complex mathematical formulas.
It has a direct impact on the shine of the stone. The more well cut a stone is, the more shine it will give.



The carat is the unit of measurement for the weight of a diamond (WEIGHT).

1 carat is equal to 0.20 grams.
This word comes from the Carob tree whose beans served as a standard of mass in antiquity.
Because larger diamonds are rarer than smaller diamonds, they have a higher price per carat.

A 1 carat stone will always be higher in price than two 0.50 carat stones.
