Why did you buy the diamond ring GIA certificate 10 years ago? Ask the great God to give pointers, did you buy a second -hand renovation diamond?

This is unlikely. Generally, high -quality diamonds will be hoarded by large merchants and gradually release later. Some advanced carat diamonds have ten years of certificates. The previous white leather GIA certificate was higher than the current gold content. Besides, although the diamond is high, it is crispy. If it is renovated and renovated, it will definitely leave traces. The carbon black generated in the waist code is also difficult to clean up.
If it is still uncertain, you can compare the relevant information about diamonds and certificates. If there may be a gap between the weight and cutting of renovation, the weight must be smaller. There may be changes. For example, the original diamond surface has a ribbon or obvious growth pattern. After re -polishing, the clarity will increase, which may make up for the lack of weight, so the value may not be reduced.
The price of diamonds is expensive, and the price is reduced when you go out. If you are interested, you can see the Belgian magic star diamond. It is also possible to issue a GIA certificate. It is mainly cost -effective. There are thousands of pieces of one -carat D color level.
