Huge brooch, possibly a sash pin, has large unfoiled citrine rhinestones and faux pearls. The brass setting is ornate with floral accents. This is not signed, but very well made. Might be Czech in origin.
The rhinestones have some scratches and flea bites. There is also some wear to the finish. Still, an impressive pin, measuring 2.75 x 2.5 inches.
