I am offering my tanzanite ring. It was a gift from my ex, and I don't actually know much about it. I do understand it's tanzanite. It isn't really sterling silver and the diamonds aren't real, but the value is the tanzanite. It's a size 6. I require some money so I need to part with it. I enjoy this ring, and everywhere I go I get complimented on it. The stone is a quite blue-purple. $20 Cash!
