Vintage Elegant Black and Rhinestone Brooch

Stunning black and rhinestone vintage brooch. Sparkling and elegant. Would also make a beautiful statement necklace if converted. (See example picture above—NOT this piece, but could be.) This was a piece owned by my friend’s mother-in-law. How I ended up with it is a long, boring story. So most of its history is lost to me other than I know it was worn in the 50s in rural North Dakota. Smoke-free, cat-friendly home. Reasonable offers welcomed.
