This beautiful alpaca pin (not sterling silver) has an inlaid abalone water lily on the top piece, somewhat stylistic, with a white enamel background. It has three teardrop-shaped drops with the same abalone, white-enamel pattern. The top has a 1-1/2 inch diameter, and the drops are one-inch long. The back of the pin is marked "ALPACA MEXICO' (though Alpaca is hard to read). I believe this is an older pin, and it is in excellent vintage condition. Quite a lovely water lily!
