New vintage jade sterling silver cocktail ring

New vintage jade sterling silver cocktail ring Minimalist simple design. Rustic industrial feel. Stripes effect! Polished Canadian jade nephrite industrial glued into the setting. Solid thick band. Not as sleek as other designs. Rougher (but not sharp) feel. May be a man’s ring but unisex by today’s standards. New vintage c. 1970s. Probably handmade in Mexico. Hallmark: STERLING SILVER AJT (?) Was black and I cleaned it up with toothpaste!
