How is the weight of the diamond calculated?

Quasi-newcomers buy diamond rings, and the knowledge of many diamond rings is certainly unclear. About carat weight and so on. How is the weight of the diamond calculated?

The weight of the diamond itself can be calculated. The quality of the diamond is judged by the internationally recognized weight, color, clarity and cut (4c), so the price has been relatively stable. Diamonds imported from the formal channels are subject to a 17% appreciation tax, a 5% high consumption tax, and a number of marketing expenses. The retail net profit is generally limited.

At the beginning of the twentieth century, the carat weight was unified and standardized globally. 1 carat = 200 mg = 0.2 g = 100 points. On the diamond certificate, the weight of the diamond is accurate to the third decimal place.

If you want to know if the diamond is worth the money, whether your diamond is replaced by a business hand or a fake diamond, the best way is to calculate the weight of the diamond yourself. There is a formula here: the cube of the diameter × 0.00366 (allows ± 0.03 carat error).

How is the weight of the diamond calculated? Now the new people must know how to measure the diamonds, so that when you buy, you can choose the diamond that suits you.
