Vintage Mid-century Rhinestone Atomic Comet Brooch

This is a fairly large unique vintage rhinestone brooch that appears to be a three-tailed comet. A few of the rhinestones appear smokey gray in color, and the center most stone is chipped. There is some tarnish, especially on the back. The piece appears to be rhodium plated, and there are a few spots on the back where a brass base metal can be seen. Overall, the piece is still in very good condition and was likely made around the 1940s-1950s. Approximate Dimensions: 2.5in x 1.75in
