Unique! Handmade Teal Stone Unisex Taxco Ring

Vintage aquamarine teal genuine gemstone, handmade Art Deco style ring! A really unusual and beautiful piece. Stamped 925, sterling silver. Estate find Featuring flower pattern stamped band and a semi-precious stone of some kind. After much research, I think it's Fluorite. Very Art Deco design. I think it's vtg Mexican, because it came with other Mexican pieces, but not 100% sure. 20 mm. 2cm Size 9. Thanks for looking!
