Here is a pin most likely made in either Czechoslovakia or Austria. The green glass cabochon stones are set into a brass-like filigree mount. The large center stone has prongs and the smaller ones are saw tooth bezel set. The pin stem fits into an elongated C-catch and is secure. The pin measures 1 7/8" in diameter. The center stone is slightly loose but is in no danger of falling out. No chips or cracks on any of the stones.
