Estate item.

Measures approx. 2 1/2" long and weighs 8 grams. It has a pat number on the pin/clasp bar. No other markings that i can see. I did test it for sterling silver and i does test at least 800 sterling silver or higher. It does not attract to a magnet. Late 1940's to early 1950's piece. Excellent Antique condition. No damage.
