Vintage 1960's Modernist Stainless Steel and Abalone Pendant and Brooch Demi-parure

Faintly honey-comb textured and antiqued stainless steel pendant and brooch each featuring a central genuine abalone plaque. The rounded square pendant is suspended in a navette formation with an oval east-west abalone focal point which appears recessed in an oval crater. The brooch is elliptical in shape and features an elliptical abalone focal point with a creased and convex bottom edge. The chain is continuous and slips over the head. Both pieces are in excellent condition.
