For the price of diamonds, please refer to Rapaport diamond quotation. When recycling diamonds, you need to consider the actual situation of diamonds and the market situation at that time to depreciate or increase the value.
Regarding the second-hand one-carat diamond ring, the quality of the diamond is different, and the price gap is quite large. The price should be estimated according to the actual diamond situation and the withdrawal situation.
Hope to adopt. Thank you.
