Gorgeous 1948 Adolph Katz Coro Rhinestone Crown Brooch

Absolutely fabulous signed Coro rhinestone crown brooch set with sparkling diamanté rhinestones in silver tone metal. This is an Adolph Katz piece, patent #150,707 from 1948. The oval stones were missing so they have been replaced and the old glue removed from the stones so it sparkles like new! There is some light discoloration on the bottom curve of the crown but no plating peeling. The brooch measures 1 3/4 by 1 1/2".
