An Art Deco diamond plaque ring is a style of fine jewellery popular during the 1920s and 1930s, characterised by an elongated, geometric panel or plaque face set with multiple diamonds and featuring detailed metalwork.

Art Deco plaque rings were predominantly crafted from platinum or white gold to showcase the white brilliance of diamonds. Construction techniques included hand-pierced filigree, grain setting, and millegrain edging.

Authentic pieces from the Art Deco period feature hand-finished details such as fine millegrain borders, geometric symmetry, platinum hallmark stamps, and period-correct diamond cuts like Old European, Single, or Transitional cuts.

An antique diamond plaque ring can be worn as a statement cocktail piece or as an alternative vintage engagement ring, pairing effortlessly with both contemporary tailored attire and evening wear.

Clean the ring gently using warm water, mild dish soap, and a soft-bristled brush to remove dust from behind the settings. Have the stone prongs inspected annually by a professional jeweller to ensure long-term structural security.
