Lab Created Diamond Carat weight
The more a diamond weighs, the larger it will be. Because large diamonds are rare, they generally have a greater value per carat – though the other quality factors of cut, color, and clarity can also affect price. The term "carat" is derived from the carob seeds that were used to balance scales in ancient times. There are 100 points in a carat, thus a half-carat diamond can be referred to as a 50-point stone, for example.
