An antique large Rock Crystal set in a 9ct gold filled brooch mount from the early Victorian/Georgian period. It’s unmarked but tests as 9ct. The Rock Crystal has been tested on my presidium 11 gem testing machine and it has a peach foiled back. It measures 26mm x 21mm and the rock crystal gemstone measures 18 x 15mm and the brooch weighs 10.79 grams. Condition is good considering how old it is. Dispatched with Royal Mail special delivery.
