Stickpins' traditional purpose was to secure a tie or scarf but they are now currently worn as a lapel ornament, either singly or in groups. The motif atop these pins can vary widely from a simple pearl or gemstone to whimsical designs such as animals, horseshoes, flowers, gold nuggets, mythological creatures, bugs, busts, cameos, just about anything. Stickpins all have one thing in common, the long pin that completes them. This pin can be straight or twisted (for security) and sometimes has a protective cap to place over the pointed end to help keep the pin in place.
This incredible example features sparking old cut diamonds approx. .50 ct., a central cabochon fiery opal with play of color and a halo of demantoid garnets in what looks like, hi karat gold.
The frame and mounting tests for 18k and pin stem is 14k..
The pin complete with stopper measures 2-5/8 (length) x 5/8 x 1/2 inches (top).
A lovely piece...
The condition is very good with negligible wear commensurate with age. Note: opal could use a polishing, garnet untested but is likely demantoid given the period.
