Gemologists and jewelers evaluate the physical characteristics of diamonds using the "Four C's" classification system:
- Cut
- Carat
- Color
- Clarity
Using the Four C's, the jeweler may determine the value, estimate the cost, classify the rarity, and know almost all basic information of the diamond.
There are several large laboratories that grade diamonds in the industry such as: GIA, EGL USA, IGI, GCAL, HRD, etc. The diamond labs classify a diamond. Ultimately, a diamond is priced on what the market will bear. There is no better way to price than the international market that consists of electronic exchanges and diamond centers in New York, Antwerp, Mumbai, etc.
