When you own a diamond of this carat weight, you can name it whatever you like.
All diamonds -- each with its own carat weight -- are 100 percent diamond.
The diamond either weighs 100 points, or a full carat, or it weighs 80 points or 80/100ths of a carat.

A one-half carat diamond weighs 100 milligrams = 0.10 gram.
1 Carat = .2 grams = 100 points
A one carat diamond equals 100 cents when measuring diamonds in both carats and cents.
'Cents' or points usually describe diamond weight that less than one carat. One carat equals 100 cents or 100 points.
As far as gemstones are concerned, carat (karat) is used to measure their weight (as opposed to metals where carat refers to purity). There are 100 points (pts.) to a carat so a 1.0ct diamond is equal to 100 points; a half carat diamond is equal to 50 points and so on.
One carat equals 100 in this example. If the diamonds are of equal size, then each diamond weighs 4.5454545 carats.
A 15/100s carat diamond is on the small side for a single diamond; you may be able to purchase one for US$100 - US$500, depending on its colour and clarity.
