Vintage Signed Hattie Carnegie Prong Set Black Rhinestone Floral Brooch

This is a beautiful prong set rhinestone brooch with black navettes (flat top with side facets) set in a "japanned" setting 

This brooch is marked "Hattie Carnegie" on the back

I did see a couple small nicks/chips in one of the navette stones (outer edge) and the largest round stone

The last picture with the small yellow lines is where the chips are but they are Not very noticeable!
