What is Carat?

Carat is a weight unit. The abbreviation of a carat is `ct’. It is used to convey the diamond’s weight and other related gemstones.

1 carat = 0.2 grams or 200 milligrams

One of the most prime points that must be kept in mind is the weight of the carat is not similar to volume or size of it. Each gemstone has its own densities. This is the reason, a diamond which is one carat is not necessarily needed to be big like the other gemstone of a similar carat weight.

How to calculate a Diamond’s weight?

The diamond is calculated by weighing the stone and is then recorded in grams weight. That weight is divided by 0.2 to obtain the diamond’s carat weight.

For instance, a diamond weighing 0.1 grams, it is divided by 0.2. The resulting number is 0.5, which means that the stone weighs half a carat.
