The 4 C’s - Each Diamond is Unique

Each diamond is unique and therefore each stone has its own individual value, which is determined on the basis of four criteria, the "4 C's":

C for "carat": Originally diamonds were weighed with the dried seeds of the carob tree. Their weight is constant: 1/5 gram (0.2 gram) = 1 carat. A round brilliant diamond of one carat has a diameter of about 6.5 mm.

C for "colour": Among the white diamonds, the freedom from any hue gives the highest value. A scale, established according to international rules, allows each diamond to be classified between the finest white and a tinted white.

C for "clarity": The diamond often carries traces of its dramatic formation: inclusions. And so a for a scale from "pure" to "piqué III” was created. It allows for an accurate assessment, taking into account the number and the importance of its inclusions.

C for "cut": A strict assessment ensures that the precision, polish and proportions of the diamond have been carried out according to strict criteria.

The rule of the "4 Cs" could be supplemented by a fifth C: the C for "confidence", the trust of the customer in the members of the Swiss Gemmological Society.

The crystalline clarity and dazzling fire of the diamond symbolises the munificence of Creation.
