The listing, CZ engagement ring has ended.
I'm not sure where I purchased this. It is definitely CZ. Emerald cut in center with two smaller stones to either side that are round. It is not stamped - it's most likely silver tone. It show's a little wear - I was cleaning out an armoir of mine and found it in the drawer with some other costume jewelry. Would make a nice right hand ring or engagement ring. Never turned my finger green though. Could use a little cleaning.
