How can people who don't know diamonds buy them?

For the record, the following opinions are all my own experience in buying diamond rings, which may not be completely correct, but they should not be wrong, because I have done a lot of work in buying diamond rings myself. Ha ha. ..

Diamonds mainly look at 4C, that is, weight, color, clarity and cut.

1. It depends on the size and price you want to buy. Now it sells well for 30 minutes and 50 minutes. Go to the jewelry store to try on the diamond size and choose according to your own requirements.

2, color points DEFGHIJKLMN. It is best to choose the color above H, because the color below H will be slightly yellow, and the bigger the drill, the more obvious it will be. If you bring your own, FGH has the highest cost performance. If you collect, choose the best D color.

3. Clarity grades are divided into FL, IF, VVS 1, VVS2, VS 1, VS2, SI 1, Si2, P 1, P2. If you take it with you, VS is the most cost-effective. Don't choose the grade below Si, the defect is too serious, which will affect the beauty of the diamond. If you collect it,

4. The cutting grades are divided into EX, VG, G, F, and P. Whether you bring it yourself, collect it, cut it, polish it, or be symmetrical, you must choose EX, which is called 3EX cutting for short. In short, if you buy diamonds, you should mainly look at the certificate. Don't blindly believe in brands. Big brands don't necessarily sell good diamonds. Mainly depends on the certificate of diamond. GIA certificate is the most authoritative in the world. NGTC certificate is the most authoritative certificate in China. The waist of each diamond will be engraved with a number by laser. Just compare the number on the diamond and the number on the certificate correctly when buying. Generally, no one makes fakes because the cost is relatively high. But remember to compare them correctly and check whether the diamond information is consistent with the certificates in official website and GIA. There are so many directions. Nothing.
