Hi, I'n new here. I need your help. Let me explain. Last week my boyfriend proposed to me, yes he presented me with a ring, but no I hated it. So I told him so. He bought it at Christies, the auction. Its a 9ct marquis diamond with 2 smaller trillon cut diamonds flanked. He said if I wanted to I could sell this item at an auction in London along with matching earrings and necklace and could buy or make a new ring to my standards. I want to know where online I can find exotic rings that are expensive and beautiful. I don't know where I can find these items. Please Help.
