This vintage brooch has a gold-filled setting which holds a very large smoky quartz faceted oval gemstone.
The frame is 1 ¼” by 1” and has a pierced design simulating twisted ribbons within a beaded border.
The smoky quartz measures approximately 25mm x 17mm and is about 24 carats in weight. It has even, deep color and no visible inclusions.
On the back is the plaque stamped “1/20 12K. G. F.”. The pin has a safety clasp. Condition is very fine.
Smoky Quartz is the birthstone for those born in November, the gem for Scorpios.
