Diamond Carat

Carat is the measure of a diamond's weight. The basic rule: One carat is divided into 100 parts, called points, and described by the number of points or as a percentage of a carat. (For example, a diamond weighing 75 points is described as 3/4's of a carat.) Keep a diamond carat size chart handy when trying to decide how big or small you want to go.

Splurging on your fiancée-to-be? Check out 2-carat engagement rings to make a stunning statement with head-turning diamond sizes. You'll find rings with clusters of stones, chunky solitaires and three-stone settings. Also consider 1-carat engagement rings and complementary bands for a breathtaking combination any future wife would love. Be sure to look for diamonds under 1/2 carat for just the right amount of shine to accent a colored gem or birthstone.

Since a precious stone's value rises when its weight is increased, diamond carat size has become the most recognized of the 4 C's. Keep in mind, weight is only one factor that determines a diamond's value; it's the combination of all 4 C's that determines the value and price. All gemstone carat weights (ct. t.w.), if mentioned, are approximate; variance may be up to .05 carat.
