The listing, Sterling Ring with Blue Tigers Eye Stone SZ 8 has ended.
Unisex sterling silver ring with a striated blue stone. Inside the band "STER" is stamped but it does NOT say 925. The blue center stone has light and dark lines through it that reminded me of tiger's eye stones. I think the stone it is likely organic in origin. It is a size 8 ring but would probably fit up to 8.5 with no problem. It was a gift so I know nothing else about it's history.
