Diamond & Opal Pendant/Brooch

This fabulous mid-19th-century European Opal and Diamond pendant/brooch dazzles with 4.25ctw in diamonds. The Old Mine cut diamonds dazzle as they give the appearance that they're floating around the opal. The pendant is silver topped in 14kt yellow gold. This pendant also converts into a Brooch: the bail unclips and a pin stem is screwed on the backside to become the brooch. Rare and unusual Opal Pendant/Brooch.
Circa 1850.
