Vintage OLD exquisite Bisbee turquoise sterling squash blossom ring sz 7 40's

The estate owner that had this and a few other pieces I got said that this is a very old ring, the look and feel and high quality silversmith construction tells me it's pretty old, this was said to be from around the 30's, 40's. This is an exquisitely made ring , the leaves are a 3D see side view, Bisbee bezel set turquoise with a rope trim, double shank band, and it's a weighted 8.9 grams! This is a size 7. It was cleaned years back but it is getting it's aged patina back on it, I can polish it to be bright shiny if you like. I would leave it as is if it were me to age tobthst old black patina! This has many handmade details and is truly a work of art by the silversmith. Bisbee has not been mined in over 40 years! box 30 I sell in my closet and have tons of other brands similar to list such as weiss, Stanley Hagler, Alice caviness, Demario, Navajo, James Avery, miriam haskell, Jomaz, hattie Carnegie, juliana, Lee sands, Barse, native American, Navajo, Fairchild Baldwin, coro, vior,Donald stannard, lisner, renoir, Eisenberg, Christian dior,Givenchy, ciner, carolee's, hobe, Ben amun, Tiffany and co, Vendome, Alexis bittar, Judith jack, kjl, vargas, Sherman, Nolan Miller, Elsa peretti sharra Pagano, Jill Fagin, raebird, Jay feinberg, kenneth Jay lane, Germany, talbots, Lilly pulitzer, J. crew, Japan, Hong Kong, Simon ju, Thelma deutsch, Erwin pearl, monet, Napier, Cynthia Daniel, Judith McCann, hollycraft, Joan rivers, Elizabeth Taylor, Anne klein, Oscar de la
