Silvertone Purple Bling Ring

Excellent preowned condition! This was a gift from an awesome fellow posher who tolde that she wore it for years and it never tarnished. Maybe it is stainless steel? sterling silver? It is very pretty and might be real sterling silver or mixed metal? However I don't see a 925 stamp. Not sure of size. I think it's a 6/7? It is beautiful, I just don't wear it. Make an offer! Bundle and save!!
