Our lab grown diamonds are optically and chemically indistinguishable from natural diamonds and vary in quality among the 4Cs. Lab diamonds are graded, appraised, insured, and resold just like mined diamonds. Learn about the future of fine jewelry.
The carat weight of a diamond is a measurement of its weight. One carat is exactly one-fifth of a gram (0.20 g). When a diamond is properly cut, the carat weight defines the size of the diamond. When it comes to smaller diamonds, an Ada concierge may use the term “points” to discuss diamond weights.
