Every diamond has distinct characteristics. The 4Cs – color, clarity, cut, and carat weight –
are the recognized standards for determining the quality of a diamond.
The color refers to the natural tint that white diamonds can have. Clarity measures the purity and rarity of the stone.
The cut grade of a diamond is determined by its proportions, finish, and also by how the facets interact with light.
At the very least, the carat refers to the weight of the diamond.
