Scottish Victorian Silver/Montrose Agate Pin

Definitely a unisex item, this is an exquisite silver pin. The stone is gray agate from Montrose on the east coast of Scotland, set in beautifully engraved silver surrounded by silver dragooning (silver balls). Age has not affecting this beauty in any way and the stone is as shiny as when it was set. There is a "C" clasp with the sharp longer pin as of the Victorian era when clothing was made from wool.
The pin measures 1 1/2 inches by one inch and can be worn in different directions or your jewelry could easily make it into a stunning pendant? On man's jacket this would also work.
