Carat Weight
Carat is easiest of the 4 Cs to understand and quantify, because it’s simply a matter of weighing the diamond. One carat has 100 “points.” So, if a diamond has 75 points, it weighs 0.75 carats.
Generally, a diamond’s size increases as its weight increases. But higher carat weight doesn’t mean higher quality. Fine quality is found in diamonds of all carat weights.
At Mervis, we rely on the most accurate electronic scales to determine carat weight. And we never round up or down. You’re told the precise weight of every diamond you inspect. We’ll weigh it right in front of your eyes!
