This is a stunning Brooch/Pin that really sparkles, indicating they are most likely Austrian Crystals. Craftsmanship is very detailed and high end. No signature. Very good condition showing little to no wear. Measures roughly 1-3/4" x 1-3/4". It will be shipped in a gift box and I can gift wrap.  See my store for more jewelry and vintage items. https://ebay.us/m/KTQYv9
