An Art Deco diamond drop pendant from 1920, fashioned in platinum and white gold with a silver colour finish. The piece comprises a 1.00 carat old European cut diamond set in a claw mount above a scalloped back plate, suspended from a slim bar and a triangular bail set with a small eight-cut diamond. The pendant connects to a trace chain. From top to bottom, the pendant measures 2.5 cm. This piece is suitable for everyday wear or special occasions as part of a jewellery collection, and works well when worn at the neck with evening attire or smart daywear.

FAQs

Art Deco diamond drop pendants created around the 1920s are characterised by geometric linearity, vertical suspension designs, and white metal settings designed to highlight brilliant gemstones.

Pendants from this era were typically constructed using platinum or white gold, featuring hand-cut diamonds such as old European or single cuts set in delicate claw or bezel mounts.

Authentic period pieces feature old European cut diamonds with open culets and steep crown angles, geometric drop mountings, hand-finished settings, and historical hallmarks on the chain or bail.

An antique diamond pendant offers clean geometric proportions that complement minimalist contemporary necklines as well as formal eveningwear.

Clean the piece gently using warm water, mild liquid soap, and a soft-bristled brush, avoiding harsh chemicals, and store it separately in a lined box to prevent scratching.
