The price of a diamond is usually determined by its quality and size. The price of a carat diamond in the market is basically between 20,000-10.2 million. Why is the difference so big? It's the quality of the diamond (color and cut). Irregular diamonds are at least 20,000-30,000, and the quality is relatively poor. Generally speaking, it is more than 50 thousand (round diamond), with very good color and exquisite cutting.
In terms of weight, carat (Ct) is the unit of mass (weight) of diamond valuables, and now 1 carat is equal to 0.2 g or 200 mg. One carat is divided into 100 cents, such as 50 cents or 0.5 carat, used to calculate smaller diamonds. Because the density of diamonds is basically the same, the heavier the diamond, the bigger the volume. The bigger the diamond, the rarer it is (the largest diamond in the world), and the higher the value per carat.
