This is a fabulous and early pin which was made by SANDOR of sterling silver. The piece is also hallmarked STERLING.
The ribbon watch pin hook top is gold vermeil as is the bottom round portion. The bottom is comprised of red diamond shaped glass rhinestones which have a very unique facet to them. The middle is filled with clear rounds.
The pin measures 2 1/8" by 1 3/4". Condition is quite good. Needs a polishing if desired.
