Vintage Southwest Ring Coral Turquoise Lapis Size 6

An unusual vintage ring...featuring what appears to be resin enhanced coral turquoise and lapis stones. there are no hallmarks on this ring so we had it acid tested and it confirms as sterling silver. It appears that it could have been sized at some point in the past, and that process erased the hallmark. This very often happens. Size 6 What a Unique ring! Price firm, thank you.
