Vintage Gold Sparkle MCM Pin Brooch Pin West Germany Leaf Amber

This is a gorgeous pin marked "Made in Germany West." To me, it has a very mid century feel. I'm not sure if the main triangle shapes are made with enamel or perhaps mother of pearl. The main stones are very sparkly and iridescent. The stones in the leaves are a gold/amber color. There is some mild tarnish on this pin but overall it's quite stunning. Measures roughly 2-1/2" x 2-1/8". Thanks for looking!
