if i was guessing i would say its around latter 70's to early 80's, i collect old antique turquoise jewelry. judging by the style and aging , its is great condition someone really took care of it. and if the dime fits around the band its about a size 4.5 to 5. very beautiful piece i will be bidding in the end. good luck. and thanks for having such a lovely piece.
Lotsa competition but that's what it is about. I have very small fingers and I have really looked hard for awhile here to find this size AND a native piece. I'll be praying at the end of bidding for sure! Beautiful ring.
