This is such a beautiful ring, only worn a couple of times.  I believe it is green tourmaline but could be chrome diopside. . .beautiful
faceted large stone.  It is a Size 5 (see pic of ring on sizer.  It is hard to see the hallmark inside but I think it reads  18K GP so it
has a nice weight.  Some days my pics are  not so good, so will try to get better ones tomorrow.  I have a some free home.

Please ask questions before bidding, as all sales are final.  I only ship to the lower 48 states.
