Vintage Alpaca Mexico Abalone & Mother of Pearl Flower Diamond Brooch & Pendant

Vintage Alpaca Mexico Abalone & Mother of Pearl Flower Diamond Brooch & Pendant. Very eye catching piece. Diamond shape with triangles framing each point. Triangles are abalone. Center is a vibrant purple blue with abalone leaf inlays and mother of pearl flower. All back in Alpaca silver and stamped on the back. "Mexico" is readable and it likely says Alpaca above it but worn off. This is a brooch that also has a pendant option. Artisan made. Very good pre-loved condition with only light wear. See photos for measurements and condition questions.
