WHAT IS CARAT?
A carat is a unit of mass used to measure gemstones and pearls. Its mass is equivalent to 200 mg (or 0.00643 troy oz). The Greek term for a basic Carob tree, Ceratonia siliqua, is where the word "Carat" first appeared. Diamond traders once compared the weight of a diamond to Carob tree seeds before measuring units were created. This was due to the uniform size and weight of each carob seed, which made them a reliable and practical marker to gauge the size of diamonds against.

Because of this, jewelers frequently add the carat weight to a ring's shank. This may be seen in products like diamond Trilogy rings and even large diamond clusters. For identification purposes, the total carat weight is occasionally added in place of the specified individual diamond weights.
The words CTW and a number (the total carat weight) may be stamped into a concealed area of some jewelry items. This makes it simple for jewelers to determine the overall carat weight of a certain piece. even without having to take the stones off their mounts to weigh them.
HOW TO SCALE CARAT WEIGHT?

You must weigh a loose diamond and note its weight in grams before you can determine its carat weight. After that, multiply that result by 0.2 to determine the diamond's total carat weight.
The opposite is also true. Add 0.2 to the carat weight to get the exact weight of a single diamond or a group of diamonds. The equivalent total weight in grams will be yours.
