The brooch secures to the reverse with a double pin and sliding catch.


This Art Deco brooch has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone.


This stunning antique brooch is exceptional quality set with very high colour graded diamonds, displaying a fine white colour, brilliance and presence.

The brooch is an exceptional gauge of platinum and is in excellent condition.


Reflections in photographs may detract from the true representation of this fine example of antique diamond jewellery.
