Art Nouveau Revival Sterling Silver Baltic Amber Pin Brooch

Executed in an Art Nouveau Revival manner, here's a sterling Silver (tested, not marked) pin brooch designed as a single flower with a round 5.5mm cab of Baltic Amber. Size of the pin is 1-3/8" high x 1/2" wide. Weight is 2.3 grams. Safety catch closure to hold the pinstem in place. Condition is very nice with no problems I can spot.
