carats
Jeweler's mass measures
Carats are units of weight for gemstones, equal to 200 milligrams.
A five-carat diamond is larger and typically more valuable than a one-carat stone.
The term also appears as karat when measuring gold purity, where 24 karats represents pure gold: an 18-karat gold ring.
The spellings are often used interchangeably, though American usage tends to distinguish them.
