Vintage Sapphire Stick Brooch - Starburst Lapel Pin - Tested Genuine

Genuine tested sapphire. Tested on a presidium gem machine. See photo. White/clear stones test as crystal which are also on the gemstone scale but they aren’t diamonds. Pin has a very small bend on the lower part of the pin prick. Does not affect wearability. Nice vintage piece. Metal is untested and unmarked so it may be gold plated.
