Understanding Diamond Quality: The 4Cs
The value and beauty of a diamond are determined by four key characteristics known as the 4Cs.
Cut
The cut determines how well a diamond interacts with light, affecting its brilliance and sparkle. It’s considered the most important of the 4Cs.
Color
Diamonds are graded on a color scale from D (colorless) to Z (light yellow/brown). The most valuable diamonds are those with the least color.
Clarity
Clarity refers to the absence of inclusions and blemishes in a diamond. The fewer the imperfections, the more valuable the stone.
Carat
Carat refers to a diamond’s weight, not its size. One carat equals 200 milligrams, and diamonds are priced per carat.
