Vintage 50s Sterling Silver, Marcasite & Fiery Opal Floral Brooch

Vintage 40s or 50s solid silver, marcasite and fiery opal floral brooch. 6cm tall, 14g in weight and the opal is 1.2cm tall. The opal doublet is beautiful and very lively. It has a blue backing so flashes blue as well as red. Good vintage condition with all marcasites present and only one of them is chipped. The marcasites are part claw set and part glued in. Stamped underneath 'Sterling Silver Foreign'. The clasp works well. It has not been cleaned but it can be…just let me know. A beautiful piece of vintage jewellery.
