Large vintage Art Deco Czech rhinestone brooch, topaz orange / citrine yellow paste stones in a gorgeous floral design

Vintage Art Deco brooch with a beautiful flower design on a silvery, very pale antique gold tone filigree base. I would say its appearance in natural light is probably more antique silver tone than gold. There are lots of yellowy orange rhinestones, claw / prong set in the piece, some as centres of the flowers. The detail in the flower petals is lovely, with subtle lines of orange, probably enamel paint, down the centre of each.

This piece is an Art Deco piece from a Czech / Gablonz maker - the quality is akin to pieces by the Neiger brothers, but the component parts and construction are not quite right for Neiger, in my opinion. Of course I could be wrong as so little is really known and there is much speculation amongst collectors.

This brooch has a length of 3 inches, and it is 1 3/4 inches wide. It is in very good vintage condition.
