Diamond is a kind of natural precious mineral, which has become high-grade jewelry after processing and polishing. Color, clarity, weight and cut are the four criteria that affect the quality of diamonds. Weight, also known as the "carat" grade of diamonds, represents the size of diamonds. Carat grade was put forward by J. john J.Bergerduff in the early 20th century, which refers to the weight unit of diamonds. The Klajo of 1 is equal to 0.2g, and the quality of diamond increases with its weight. Therefore, the carat grade of diamonds is one of the basic standards to measure the size and quality grade of diamonds.

The weight of a diamond is one of the factors that affect the price, so the carat grade is particularly important when choosing a diamond. On the one hand, if you want to buy a large carat diamond, you need to choose between quality and price; On the other hand, the quality of diamonds should also conform to common sense. It is best to choose high-quality diamonds, and the quality will not be reduced because of the pursuit of large carat level. Therefore, diamond buyers should combine their own needs and economic strength to choose the diamond carat grade that suits them best.

The carat grade of a diamond not only represents its size, but also is closely related to its quality and value. In the field of investment and jewelry collection, a high-quality diamond with a large weight can often become a treasure sought after by collectors. But in daily wear, the weight of diamond is not the only factor to be considered, and its quality, such as the cut ratio, is more important. Therefore, when buying diamonds, don't blindly pursue carat level, but take quality as the leading factor and choose the gems that really suit you.
