Choose a style. Needless to say, I just like it. Select materials. General diamond ring materials are divided into PT950 and 18K. There is also the material of PT900, which is relatively rare, so I won't mention it for the time being. Then there is gold, but the hardness of gold is not high, and generally no one will use it as a diamond ring. PT950, commonly known as platinum, is the first choice for wedding rings because of its high purity and low hardness but higher than gold. Then 18K and 18K are divided into three colors, k red, k white and k yellow. K white is not much different from PT950 in color and feel. Personally, I suggest that the diamond ring material is 18k white, which has high first hardness and is not easy to peel off compared with PT. Second, it is cheap. If ordinary people don't look at the printing on the inner wall, it is difficult for the naked eye to tell the difference between 18K and PT. Generally, people in the industry choose diamonds by looking at the color first, then the clarity, then cutting, and finally touching the wallet to pick the score, that is, the weight. I won't talk about the weight. Of course, the bigger it is, the more expensive it is. I won't say anything about it. If I choose a drill when I get married, I must have 3EX, which means perfect cut, because this kind of cutting drill will blind my dog's eyes. The other three standards can be lower, but I will never give in to cutting. Now let's talk about other 2C. If the subject is as cost-effective as I am, it is recommended to choose E or F color, and the definition should be SI 1 (or VS 1, Vs2). Please don't think his clarity is low (please ignore my suggestion). When inlaying, you can let the stone inlaid master grasp it with a ring holder. Even if you can't stop it, please believe me, as long as you don't stare at him with a magnifying glass for 24 hours. Oh, by the way, the most common diamond certificates are Gia and EGL. If you don't understand them, please go to Baidu yourself. I won't explain it any more. Typing with a mobile phone is too tiring. The general difference between GIA certificate and EGL certificate is that if diamonds of the same quality and size are GIA certificates, if they can sell 1000, EGL can only sell 7000. This is a rough metaphor, as long as everyone understands it. A diamond ring is diamond jewelry worn on your finger.
