Oval pin with beveled edge. Unknown if this is real tortoise shell from a Hawksbill turtle or faux tortoise shell (celluloid). Translucent, mottled surface of browns and pale yellow. On top is a carved-out oak leaf. In center of leaf is a small gold pin that goes through to the back. Tube hinge and a modern safety clasp that is from earlier than turn of the century. Likely a replacement as it is set on top of the plate of what may have been a c clasp. The pin extends beyond the clasp. 2 3/16" long 1 3/4" wide
