Vintage Native American Sterling Carved Turquoise Frog Ring, size 7.5. Signed only with a "M". Not totally sure of artist but most likely Navajo? & I think it's a older peice. The inside was completely dark black with tarnish so I polished it slightly to reveal a markers mark.
Stone is genuine Turquoise & you can tell it has some age to it when you look closely in person.
