Found a pretty good looking ring today. The 'stone' looks really good. I would like to think its a gemstone. However the ring it's self looks really weathered.
looks like 'purple ice'. different colors of 'ice' rings were pretty popular back in the early 90's. they are simply colored and cut glass, some being made from recycled glass. I have no way of saying for sure that is what yours is, I'm just saying that's what it looks like
