Early Hollycraft brooch in the Austro-Hungarian style with faux pearls, red and green rhinestones, Peking glass? ovals, and tiny enameled flowers.  The center that resembles Peking glass is surrounded by a ring of tiny seed pearls and dark blue rhinestones. The brass chains that connect the two pieces are brass colored while the top and bottom sections have a more silver color.

4.25" long by 2.25" wide.
Unmarked but recognizable  (period before Hollycraft started marking their jewlery)

Locking clasp functions well.

Condition is very good overall.  No missing stones.  It appears the finish on the six larger faux pearls has worn off with the exception of one that still has its original golden color.  If you examine the other pearls, you can detect a smidge of the same golden color at some of their bases. 
Does not detract greatly, mentioned for accuracy.
