This is a lovely antique 900 silver Austro Hungarian brooch featuring an opal center cabochon, 4 square carnelian stones, plus several small seed pearls and selective blue enameling. The brooch bears a tiny hallmark on the C clasp. I can make out a capital letter A which is probably for the Vienna. The setting is otherwise unmarked. It tests positive for silver content slightly below sterling grade and is estimated to be 900 grade silver. The brooch has a typical pin stem and old fashioned C clasp.
This brooch weighs 11.3 gr. It measures 1.5" x 1.5". The center opal stone measures slightly over .5" x .375".
Condition is good. The silver has a gold wash that is somewhat worn away.
Make this elegant antique brooch your own special statement piece.
