David Badman Sterling Silver Mixed Metal Earrings Vintage

Beautiful in excellent vintage condition. Designer David Badman creates interesting geometric modernist designs with sterling and mixed metal. Button top appears to be brass, bottom square is sterling with brass or gold tone squiggle. Handmade. Purchased at a boutique in New Mexico late 80s(?) Not worn due metal allergies. Couple tiny spots of tarnish as can see in pictures. Don’t have box or romance card, but is hallmarked ‘Badman’ and ‘Sterling’.
