All Schreiner jewelry was hand set, often with unusual art glass stones and quality rhinestones reversed in their settings Schreiner closed in the 1970s, possibly because of their costs of making these wonderful pieces. This brooch has a green translucent center art glass stone with inclusions which matches one leaf. The petals are inverted rhinestones in light and medium blue. The three leaves on the right are pear shaped and inverted. All the leaves are in an open backed setting. 3" by 1 7/8" with a sturdy safety clasp. Marked Schreiner New York on a cartouche. Excellent vintage condition.
