THE GUIDE TO DIAMOND

LUCKY ONE diamonds are certified of high quality and meet the best selection standards. Below you will find methods for recognizing the main characteristics of diamonds, more commonly known as the 4Cs:

CARAT

COLOR

CUT

CLARITY

The analysis of these 4 characteristics will make it possible to assess the quality and value of a diamond, but also to recognize synthetic, fake or treated stones. However, complete mastery requires years of practice and the best way remains laboratory analysis. Many laboratories are internationally recognized as the
GIA “Gemological Institute of America” 

CARAT

Precious and fines stones are sold by weight, called the carat (ct), not to be confused with the unit of measurement for the purity of gold “karat”.

1 carat = 0.20 g = 0.035 oz

5 carats = 1 g = 0.007 oz

COLOR

Whether for diamonds or other stones, color is one of the most important factors to consider.
Because of course, color is one of the first things that catches the eye, and will be representative of the quality and origin of the stone.

CLARITY

Each gemstone is natural and unique, which is why the clarity of a stone has a significant impact on its value.
We speak of clarity to define the internal characteristics of a stone, that is to say its defects.

CUT

It is important not to confuse the cut with the shape of the stone and its perimeter. The term “cut” used in jewelry sets the proportions of the facets and the finish of the stone. A well-cut stone will have all its proportional facets to optimize the fire and brilliance of the stone.
