bulk wholesale aromatherapy stainless steel diffuser jewelry The diameter of the standard round diamond -cut 1 carat diamond is 6.5mm. However, the actual diamonds on the market are always small in diamonds. 1 carat diamond diameter diameter is 6.4 or 6.3mm, or even 6.0mm.
During the measurement of the diamond weight, 1 carat is equivalent to 100 "points" (PT), so that carat weight is accurate to two digits after the decimal point. Jewelry dealers can directly describe a diamond with a weight of less than 1 carat. For example, the diamonds of 0.25 carats are also called "twenty -five points". But for diamonds of more than 1 carat, you can only use the accurate to percentage "carat" to describe it.
extension information: 1 carat = 200 mg = 0.2 grams. In the old gem book, one carat is about 205.3 mg. If it is converted to the current carat, one carat must multiply 1.0265. Here is just a rough saying that the carat value in the old countries or regions is different. Diamonds with a weight of less than 1 carat usually use "points" as a measurement unit, 1 carat = 100 points. In the diamond certificate, the weight of the diamond is accurate to the third place after the decimal point. Reference materials Source: Baidu Baike Clar (Quality Unit)
