1920’s era platinum and gold Art Deco diamond brooch. Hand made in the 1920’s, this Art Deco diamond brooch utilises the wonderful ability to draw the platinum into a fine wire and still remain strong. Art Deco jewellery of the 1920’s to the 1940’s often used platinum for this reason. This Art Deco brooch is set with both European cut diamonds and rose cut diamonds. Destined to look amazing on any outfit, there is nothing quite like a genuine Art Deco piece of jewellery.
