How much a diamond ring of more than 10,000 yuan can sell depends mainly on the quality and workmanship of the diamond ring. Normally, it can be sold for one-third and one-quarter of the original price, that is, 3000 to 4000 yuan. The 4C quality of diamond ring, such as clarity, cutting and damage, is excellent and well-preserved, and the recycling price is high.

It should be noted that this is only an estimate, and the specific price needs to be determined in combination with the actual situation and market demand of the diamond ring. If you want to sell diamond rings, you can consult professional jewelers and second-hand trading platforms to get a more accurate valuation and sale.
