How to test the authenticity of Cooper diamond ring? I bought a 50-cent diamond ring in Xinzhou, Shanxi a few days ago. This is a jewelry brand of Cooper.
Did you buy it at Cooper's jewelry store or Diamond Cooper's jewelry store? If you bought it in the exclusive store of Cooper Jewelry, can you see if there is a rocket-like logo on the ring (it doesn't describe the shape: triangle above and cube below)? If yes, it is genuine from Hong Kong Gupeihang Jewelry Group! I hope I can help you!
