Buying vintage sterling and awesome turquoise southwestern ring, size 6.75

i'm in love with the stone in this ring and the ring is pretty amazing as well. artisan-made, sturdy, with a beautiful design. the stone is turquoise with some black and brown bits buying in the mix, very striking. ring is unmarked sterling, nicely made, and has some weight. good condition with some wear and patina.
