Is it better to drill square or round? Generally speaking, they can't be judged by their appearance alone, but by their quality.
First, look at the weight of diamonds. Under the condition that the clarity, color and cutting work of the square drill and the round drill are the same, which one is heavier, then choose which one is better.
Second, look at the purity of diamonds. The purer the diamond, the better the quality. For example, a round diamond with a clarity of VVS 1 is better than a diamond with a clarity of VS 1.
Third, look at the color of diamonds. The color of diamonds is very important. The colors of diamonds are divided into: D (completely colorless), E (colorless), F (colorless), G-H (nearly colorless), I-J (nearly colorless) and K-M (? Dark color), N-Z (dark color). If the color of the square drill is E and the color of the round drill is F, then the square drill is better than the round drill.
Fourth, look at the cutting of diamonds. Diamond cutting is a very important criterion to judge diamonds. The basic cutting forms are round, pear-shaped, heart-shaped, emerald-shaped, princess-shaped, olive-shaped and oval. The standard of cutting is divided into: ideal cutting, very good cutting, good cutting, general cutting and poor cutting. If the square drill is an ideal tool and the round drill is a very good tool, then it is naturally a square drill.
Many customers told me when they were selling diamond rings that this diamond was made by Chow Tai Fook or a certain brand, and they bought tens of thousands of pieces. How much have you recovered here? Recycling diamonds mainly depends on the diamond certificate, and the price is quoted according to the quality of each diamond, mainly the 4C standard of diamonds, which has nothing to do with the brand. I suggest you go to the physical store of a regular store. Baidu can do it.
