Vintage Aurora Borealis Rhinestone & Crystal Brooch/Pendant

The brooch has a goldtone mounting and can be worn as a brooch or it has a hook for a chain to wear it as a pendant.  The entire mounting is prong-set with aurora borealis rhinestones, a large one in the center which is totally surrounded by smaller ones.  The top part has 9 aurora borealis dangling crystals, 5 larger dangling crystals hanging from the brooch. It measures approximately 2" long including the dangles, and the mounting with the rhinestones is approximately 1 1/4" wide.  It has a rainbow of colors, the rhinestones and crystals are clear aurora borealis.  It has a secure safety clasp closure.  I can find nothing wrong with this brooch.  I would rate it very good to excellent.
