UNUSUAL PLASTIC & SHELL PIN

Homemade or Jewelry Kit?
This is an unusual pin and probably
one of its kind. Why? This pin was
made from jewelry findings and
possibly came from a jewelry kit.
The large edged diamond shaped
green plastic slab, with rhinestone
accents is so sweet, but what
enamoured me was the "S" made
from sea shells and the colored
sea shells on each end with tiny
rhinestone trims. Circa 1940's
