DIAMOND CARAT WEIGHT
The first known diamonds discovered by humans happened about 700 or 800 BCE in India by the Dravidian people. In fact, this is where we get the unit of weight for diamonds, carats, from; they would weight the diamonds in relation to the seeds of carob tree.
A carat is a unit of measurement and it’s the unit used to weight a diamond. One carat is equal to 200 milligrams, or one fifth of a gram. There are 5 carats in a gram.
While there is a general correlation of weight to size, diamonds with the same carat weight can vary greatly in terms of their actual dimensions. When weighing less than one carat, the diamond’s weight is expressed in “points”: each carat is divided into 100 points, for example:
- 0.75ct. = 75 points
- 1/2ct. = 0.50ct. or 50 points
- 1/4ct. = 0.25ct. or 25 points
