FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is defined by geometric shapes, clean lines, and stark colour contrasts. Sapphire and diamond cluster rings from this period frequently feature central square, emerald, or baguette cut sapphires framed by geometric halos of single or brilliant cut diamonds.

Art Deco rings were typically constructed using platinum for the gem settings to enhance diamond clarity, often fitted to an 18ct yellow gold band. Settings frequently incorporated millegrain borders, hand-carved galleries, and bead-set halo stones.

Authentic period pieces display era-appropriate hallmarks, hand-applied millegrain textures, and period-correct gemstone cuts such as old European or single cuts. Symmetry, platinum-topped gold construction, and wear consistent with age underneath the mount are key indicators.

An antique sapphire cluster ring can be worn as a statement dress ring for formal events or as a distinct alternative engagement ring. Its geometric structure pairs effortlessly with modern unadorned platinum or gold bands.

Clean the piece gently using warm water, soft soap, and a fine-bristled brush to remove accumulation behind the gemstones. Store separately in a velvet-lined box to prevent metal contact and avoid harsh chemical solutions or ultrasonic cleaning.
