Vintage, 1950S or older large leaf pin.  This has clear, turquoise and light bluish/gray colored navette rhinestones.

I do not know if all of the stones are original, some might have been replaced.

There is some surface and age-related rhinestone wear and some plate wear.

Measures approx. 3 3/8" x 2" wide.

No missing stones, some darkening to the stones and the brass plating.
