Okay, so I admit, I'm "reviewing" an item I haven't actually received yet. However, I'm doing so I can share a tip with those of you who have voiced problems with (and those who'll inevitably have reservations purchasing this ring due to reading about) the ring turning some people's fingers green/black.

After a bit of research into the matter, I've found that there is a simple, and very inexpensive solution to this- Simply coat the inside of the band with a thin coat of clear nail polish, which will form a barrier between the metal (copper, etc) in the ring which causes the green/black color and your finger. Everyone is different, but typically you'll want to re-apply every two months or so. And it's especially handy (pardon the pun) because most ladies have some sort of clear nail polish in the house anyway (a base coat, top coat, etc.). I hope this helps!
