I visited Diamonds International (DI) at 5187 Dronningens Gade (receipt says 5184) on 4/26/17 while in town on a cruise. I purchased a new engagement ring and band for a complete set. They had to be sized down. I picked them up later, they looked great and I got back on the ship. | On the morning of 4/28/17, I glanced at my new rings and was horrified. The tanzanite ring band had turned black and the metal was rough. I was upset! | I contacted DI through email that day (4/28/17) and they sent several emails back and I responded. I have sent several emails since then, and Gener is slow to respond. | I have requested in 7 emails, that I want a refund and to return the rings. I have copies of all correspondence, receipt, and a photo of the ring taken on 4/28/17. | They will not refund my money. They said the only two options were to send the rings to NY to have them polished and PLATED and secondly, to send them back for store credit! | The ONLY resolution I will accept, is the one I have been saying in each and every email since April 28, is for me to return these defective rings and receive a full refund. | I do not want to or care to own defective jewelry, to have it plated, to have a replacement one, or to have store credit. | I do not wish to do business with Diamonds International after all the negative things I have experienced so far. | YOU, Diamonds International, sold me a defective set of rings and service, I want my money back.
