Generally, a 20-cent diamond ring costs thousands of dollars and even tens of thousands of dollars in quality, but when we recycle diamonds, we are likely to earn only a few hundred dollars. The main reason for this situation is that the 20-cent diamond is too small and there is almost no room for appreciation. Therefore, if you consider diamond recycling before buying diamonds, it is suggested that you can buy diamonds with more than 30 cents, which will have more room for appreciation and will not lose too much. In addition, it should be noted that you must ask for a GIA certificate for diamonds with a price of 30 cents. GIA certificate can be said to be the identification of a diamond, which can clearly know the quality of the diamond, so that you can buy a better price when recycling.
