After a rough diamond is mined, it is evaluated to determine its best possible cut, in order to maintain the maximum clarity, color, and carat weight. The term “cut” is often confused with diamond “shape”, such as round brilliant or princess cut.
Every diamond is composed mostly of carbon. During the heating process, other elements become trapped inside, giving each diamond its own unique fingerprint. These inclusions are what help to identify your diamond.
Diamonds range from colorless to yellow or light brown, and are sometimes found in a spectrum of fancy colors such as yellow, blue, pink and even red. The less color, the rarer the diamond; however when it comes to fancy intense colors, those are the rarest of all.
The word carat comes from the word carob, a Mediterranean seed, which has an extremely consistent weight for measuring. The greater the carat weight, the rarer and more valuable the diamond becomes.
