Sterling Silver Geometric Ring Artisan Made

Very cool ring. Looks handmade and is stamped 925 and there is also a makers mark which looks like a key but I don't know who made it. It is about 1 cm wide. It fits as a size 7. Nice weight - 5 grams. ***Please Note See Photos: There is a crack in the metal in one area so I am selling at a discount. If you don't mind a small hard to see crack you will love this ring.
