Faceted round rhinestone (Citrine?) held by prong of metal pulled from surrounding crescent of sterling silver inlaid with rhinestones. The clear rhinestones graduate from larger to tiny on each side. At the bottom is a small faceted rhinestone surrounded by border of sterling silver with a decorative edge. The pin stem is held away from the headpiece so that the fully-faceted stone can catch the light. The sterling may have been lacquered black and is chipping away now. Pin is 2 5/8" long and the headpiece is 1/2" across and 5/8" long.
