FAQs

Art Deco engagement rings from the 1920s are characterised by geometric shapes, platinum mountings, intricate openwork filigree, and hand-engraved accents. They frequently feature old European cut diamonds in square or cushion-shaped illusion settings.

Jewellers during the 1920s predominantly utilised platinum for its strength and ability to hold fine filigree detail, alongside 18-carat white gold. Central diamonds were typically paired with smaller accent diamonds set within milgrain-bordered metalwork.

An authentic old European cut diamond exhibits a round girdle, a high crown, a small table facet, and a visible open culet at the base. The setting will usually display hand-carved details, milgrain edging, and period maker marks rather than modern casting lines.

An antique engagement ring can be worn alone as a focal statement or paired with a plain slim metal band to preserve the original filigree shoulders. Modern wearers often mix platinum period pieces with contemporary silver or white gold accessories.

Clean the ring using warm water, mild detergent, and a soft-bristled brush to remove debris from the pierced filigree work. Avoid ultrasonic cleaners if the settings contain small accent stones or delicate antique claw work, and schedule periodic checks with a professional jeweller.
