I purchased the ring as a special present for my daughter’s graduation, who is nearly 24 for £280. The ring arrived, it was well packaged and had the message I had ordered. My daughter began to wear the ring. She diligently took it off before washing, sleeping or using creams. My daughter herself purchased similar ring for £17 and uses the exact same routine. I attach photos of your £280 pound ring and the £17 ring for comparison. I do not expect a ring for this amount of money to be creating green marks on the finger and loosing its coating. Needless to say, I am very disappointed.
