The listing, Avon Clear Oval CZ Ring Size 7.5-8.5 has ended.
This is an Avon Cubic Zirconia ring. It's got a sparkly clear oval shaped 5 carat cubic zirconia (no idea of the carats for the stones on either side however). Oval stone measures 3/8" (1 cm) across at widest part and 1/2" long.
The size is 7.5-8.5 because it has this little wire thing on the inside to help make it fit multiple sizes. I tried to get a good picture of it, but I think I failed.
The ring normally retails for about $25. I think it's gorgeous and doesn't look like gaudy like most costume jewelry. It's just bigger than anything that I like to wear.
This would be a great ring to use as a temporary engagement ring too since it's cheap but doesn't look cheap, it's size-able so if you don't know her ring size no big deal. And then your lady can help you pick out the ring she wants to wear long term... let's face it. What girl wouldn't like SOME opinion on the rings they will be wearing for the rest of their lives?
