I've been having issues with a friend of mine. It's a long story, but needless to say, I'm pretty sure the friendship is over. As a "pity present" I got this for myself as a reminder to "always call a spade a spade". It's 18k with 1/3ct of diamonds. Right now it's just on a silver Tiffany chain, but I have a 16" 18k snake chain on order.
