This antique Art Deco chain necklace dates from 1920. It is made from platinum and is set with five round faceted blue zircons totalling 12.25 carats and sixty-two diamonds totalling 2.70 carats. The design incorporates bezel-set round blue zircons separated by geometric diamond-set bar links, millegrain diamond settings, and a spring-loaded bolt ring fastening. The visible colours are blue and silver. The wearing length is 42.55 cm. It is worn around the neck as a piece of fine jewellery for evening wear, formal occasions, or milestone celebrations. The articulated link construction allows the chain to drape comfortably against the wearer's collarbone.

Art Deco jewellery, produced primarily during the 1920s and 1930s, is defined by geometric patterns, symmetrical lines, and bold contrast. Craftsmanship of this era frequently incorporated platinum settings alongside contrasting white diamonds and vibrant coloured gemstones.

During the 1920s, platinum became the preferred precious metal due to its strength and ability to create fine, lace-like settings. It was regularly paired with diamonds, blue zircons, sapphires, emeralds, and rubies.

Authentic pieces from the Art Deco era display fine millegrain decorative edges, geometric link construction, and period-appropriate platinum hallmarks. Settings often feature hand-cut European or single-cut diamonds rather than modern round brilliant cuts.

An antique platinum and zircon necklace provides a subtle statement piece for formal attire or simple eveningwear. Its linear design allows it to sit flat against the collarbone, layering neatly or serving as a single focal point.

Clean gently using warm water, mild dish soap, and a soft-bristled brush to remove dust from behind settings. Avoid ultrasonic cleaners and harsh chemicals, and store the necklace flat in a fabric-lined box to prevent the chain links from tangling or scratching.
