Understanding Carat Weight

See The Size On Your Hand

Approximate gemstone size on a U.S. size 6 finger

0.07 ct 33.10 ct

Carat (ct.) is the standard unit used to weigh natural gemstones, including the certified sapphires, rubies, emeralds, and other loose gemstones in our collection, and one gram equals 5 carats. Every gemstone listed on Jamsora shows its exact carat weight alongside its independent lab certificate, so you always know precisely what you're buying.

Matched pairs: when a listing is sold as two stones together, the carat weight shown is their combined total, not the weight of each individual stone.

Carat weight alone doesn't fully describe how large a gemstone will look once set, since two stones of equal weight can appear different sizes depending on their cut and proportions. For a more reliable sense of a stone's visual size, check its millimeter dimensions (length × width × depth), listed on every product page alongside its carat weight and certificate details.
