1930's Jewelled Art Deco Vintage Brooch

I am sure this beautiful art deco brooch would have started life as a fur clip with a conversion at some point to a brooch with a firm roll over safety clasp. It is a solid piece and likely to have originated in Czechoslovakia during a time when that part of the world was a prolific producer of high quality costume jewellery that was sent all over the world until WW11. Overall dimension is 5cms x 6cms, a substantial size in excellent condition especially considering its now 90 years of age.  Gift boxed by Vintageonline.
