Boucheron Quatre Radiant Edition ring in yellow gold and diamonds

The 4 criteria of evaluation of the diamond are defined by the "4 Cs":

- Cut (its size, i.e. the shape that the cutter has given it by creating facets)

- Clarity (its purity)

- Color (its color, ranging from D exceptional white + to Z tinted)

- Carat (its weight)

Gold 750 ‰, formerly called "18k Gold", is the finest quality of gold that can be found in jewelry. Note: since January 1, 1995, it is mandatory in France to use the concept of thousandths to indicate the purity of gold.

18k yellow gold (750 thousandths) is 75% pure gold, alloyed with other precious metals to make it workable. It is the most beautiful quality of gold that can be found in jewelry.

In order to easily find your ring size, we recommend that you measure your finger at the end of the day, when your finger is not too hot or too cold. Measurements may vary slightly from one hand to another.
