All diamonds are rare and no two diamonds are alike. A diamond’s quality and rarity is determined by its unique combination of characteristics of Color, Cut, Clarity and Carat Weight. The International Diamond Grading System, used around the world since its invention by GIA in the 1950s, is based on the Four Cs.
- Carat: Diamonds are weighed in metric carats. Two carats weight about the same as a small paper clip. A carat divided into 100 “points”, so a diamond 50 points weighs 0.50 carats.
- Clarity: Nearly all diamonds contain unique clarity characteristics. Flawless diamonds are exceptional and costly. Most inclusions are invisible unless magnified.
- Color: Colorless diamonds are extremely uncommon. Most diamonds have a slight yellow or brown tint. GIA uses letters to represent colors, beginning with D (colorless) and ending at Z (light yellow to brown). “Fancy colored diamonds” come in every color imaginable, are also very unusual and have their own GIA color grading system.
- Cut: While diamonds come in different shapes, such as round, pear or marquise the term “cut” refers to proportion. The well-cut, balanced diamond has unbridled brilliance, sparkle and fire.
