Description

A stunning, fine and impressive antique Art Deco 2.38 carat Burmese sapphire and 0.30 carat diamond, platinum ring; part of our sapphire engagement rings collection.

This stunning, fine and impressive Burmese sapphire ring has been crafted in platinum.

The pierced decorated mount displays a stunning four claw set 2.38ct cushion cut Burmese sapphire.

The feature sapphire is flanked to each side with a tapering baguette cut diamond, totalling 0.30cts, completing the Art Deco design.

The elevated, pierced decorated ring shoulders blend seamlessly with the plain hallmarked ring shank.

FAQs

Art Deco jewellery, prominent from the 1920s through the 1930s, is characterised by geometric symmetry, clean lines, and contrasting gemstone combinations. Platinum became the metal of choice during this period due to its strength and bright white finish, often paired with geometric stone cuts like baguettes and emerald cuts.

1930s fine jewellery predominantly featured platinum settings to secure precious gemstones such as natural sapphires, emeralds, rubies, and diamonds. Metalwork relied on precision hand-fabrication, prong settings, and step-cut side stones to emphasise linear structure.

Authentic pieces exhibit hand-finished settings, period-appropriate step-cut or baguette diamonds, and platinum stamps or hallmarks consistent with early 20th-century assay standards. Unheated or natural origin stones, such as Burmese sapphires, are typically verified via gemmological certification.

A classic three-stone or shoulder-set ring works well when paired with a plain platinum or fine diamond eternity band. Its streamlined geometric silhouette allows it to complement both modern minimalist attire and formal evening wear.

Clean the ring using warm water, mild soap, and a soft-bristled brush to remove dust from behind the setting. Store the piece individually in a lined jewellery box to prevent harder diamonds from scratching the sapphire or platinum surfaces.
