This vintage Art Deco ring dates from circa 1930 and belongs to the rings category. The design centres on a cushion-cut 4.82 carat Ceylon sapphire in a vivid, deep blue colour, held in yellow gold claws. Twelve old European and early round brilliant cut diamonds form a halo around the central stone in platinum coronet settings, accompanied by spear-shaped platinum shoulders and a slender 18k yellow gold shank. The sapphire measures 9.41 x 8.16mm, the head measures 15.5 x 15.1mm, the ring sits 8.5mm from the finger, and the total weight is 6.47 grams. The ring is worn on the hand as a piece of fine jewellery for personal adornment.

FAQs

Jewellery from the 1930s often combined geometric stone cuts with traditional cluster settings, transitioning between bold Art Deco line work and softer curvilinear forms. Central coloured gemstones were frequently highlighted by surrounding frames of white diamonds set in mixed metals such as platinum and gold.

Pieces from this period frequently combined platinum settings or shoulders with yellow gold shanks to enhance the brightness of diamonds while retaining structural strength. Natural unheated or lightly treated sapphires, notably from Ceylon, were set alongside hand-cut diamonds using claw settings.

Authentic period rings typically show evidence of hand-finishing, soft wear to the metal facets, and period-appropriate stone cuts such as cushion or old-cut diamonds. Hallmark stamps, platinum marks, and specific claw work on the central gallery help confirm historical provenance.

A substantial cluster ring acts as a focal statement piece when worn independently on the right hand or paired with unadorned metal bands. The classic blue and white contrast complements modern tailoring as well as minimalist evening wear.

Clean the piece using warm water, mild detergent, and a soft-bristled brush to remove dust from behind the claw settings. Ensure periodic professional inspections of the claws and settings to preserve structural integrity.
