2. Observe the clarity of the diamond, from minor flaws, minor flaws, minor flaws to invisible flaws, and try to choose those above VS2.
3. Diamond cutting selection, from perfect cutting, very good cutting, good cutting to general cutting, choose VG or above.
4. Judging from the weight. Carat weight, one carat equals 100 point, and 0.68 carat equals 68 point. The greater the carat weight, the higher its value. The price of carats with the same weight will vary greatly due to the above three differences.
We should discuss the price in advance. When buying a diamond ring, if you want to customize the diamond ring, if the jewelry store does not mention that you need to charge a page fee, you must be vigilant at this time.
6. Find an authoritative certificate. When buying a diamond ring, you must look for the certificate of an authoritative organization, such as the certificate of the National Jewelry and Jade Quality Supervision and Inspection Center, GIA certificate, IGI certificate, HDR certificate, EGL certificate, etc.
