Cra (CT) is the quality (weight) unit of gems, and 1 carat is now equal to 0.2 grams or 200 mg. One carat is divided into 100 points, such as 50 points, which is 0.5 carats, to calculate a small gem. Because the density of gems is basically the same, the heavier gems, the larger. The larger the gem, the more rare, the higher the value of each carat.
