The stone is a very light green, and it kind of looks like glass from an old coke bottle.  Don't get me wrong, I think it is very pretty, and I got lots of compliments on it.  I knocked a star of my rating because I think the sizing of my ring was a little off.  I ordered a size 6 (and it was marked as a 6), but it fit loose on my hand. I think it is closer to a size 7.
