HOW TO DEFINE A DIAMOND

THE “4C”

Below are the characteristics that classify a diamond accordingly to the criteria of the "4C":

CARAT – COLOR – CLARITY – CUT

There is no diamond in nature that has the same characteristics of another one. Each diamond is unique. This is what makes this gemstone so special. The criteria of evaluation of the "4Cs" - carat, color, clarity and cut – gives to our customers the opportunity to evaluate the specific characteristics of each diamond. C-Joys implements this quality rating criteria, so that our customers are able to appreciate both the value of the diamond and the jewel, where this gemstone is set and that further enhances the diamond’s splendor.
