Sterling Silver + Copper Turquoise + Flowers Statement Ring!

This is a funky, boho, lovely ring! A large copper turquoise cabochon is set between flower-embroidered silver panels. There’s no 925 stamp but I think it’s sterling silver as I’m very allergic to other metals and this one doesn’t do anything to me (however, I can’t be sure). Please see photo for sizing; such a thick ring that it’s hard to say the true size—I would say it fits me like an 8.75 (8 3/4) ring. NWOT Stone itself: Approx. ~16mm x 12mm Stone + band edges = ~20mm from top to bottom
