This Art Deco period ring dates to 1930 and is manufactured from 18k white gold. The piece centres on a natural unheated cabochon-cut deep blue sapphire weighing 2.28 carats, enclosed by a halo of single-cut diamonds. Additional small diamonds accent the tapered shoulders, whilst fine millegrain edging details the central bezel mounting. Visible hallmarks appear clearly stamped along the interior band. The ring is a size Q in the UK or 8.5 in the US. Jewellery of this type suits everyday wear as an engagement or dress ring, worn on the finger to add a touch of period glamour. It integrates easily into contemporary wardrobes, combining traditional craftsmanship with a striking colour contrast between the silver-toned metal and dark blue gemstone.

FAQs

Art Deco jewellery from this era typically features geometric forms, clean symmetry, and refined gemstone settings such as halos or target surrounds.

Rings from this period were commonly crafted from platinum or gold, featuring central precious gemstones such as sapphires framed by diamond surrounds and millgrain detailing.

Authentic pieces display official period hallmarks, precise hand-applied millgrain borders, and natural gemstones that show structural natural inclusions rather than uniform synthetic perfection.

While intended for personal wear, period fine jewellery is frequently showcased on dressing tables within dedicated glass display domes or velvet-lined trinket dishes.

Clean gently using lukewarm water, mild detergent, and a soft brush, keeping the metal work away from harsh domestic chemicals and storing separately to avoid abrasion.
