Description

A stunning, fine and impressive vintage French 9.28 carat Ceylon sapphire and 0.30 carat diamond, 18 carat white gold Art Deco style ring; part of our diverse collection of sapphire engagement rings.

This stunning, fine and impressive vintage sapphire ring has been crafted in 18ct white gold.

The substantial ring setting is ornamented with a 9.28ct oval faceted cut Ceylon sapphire, four-claw set in relief to the centre of the Art Deco style arrangement.

The central sapphire is flanked on either side with tiered, stepped shoulders, ornamented with fourteen pavé set diamonds, in a combination of Old European and eight cuts.

The shoulders meld with the feature setting and blend with the plain hallmarked ring shank.

This vintage sapphire ring is hallmarked to the outer surface of the shank with the French maker's mark and 18ct gold mark (eagle's head) and has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 18 carat gold.

The ring is supplied with an IDGL diamond and gemstone grading report card*.

This vintage oval cut sapphire ring with diamonds, is a timeless and meaningful gift. Its deep blue sapphire, symbolising loyalty and wisdom, makes it a beautiful choice for engagements, anniversaries and other significant celebrations. Elegant and classic in design, it is perfect for those who appreciate refined craftsmanship and enduring style.

NOTE: * The Gemmological Certification Services (GCS) lab has verbally accredited the sapphire originating in Sri Lanka (Ceylon).

Art Deco jewellery is characterised by geometric precision, symmetrical designs, and strong architectural lines, often featuring contrasting gemstones like deep blue sapphires set against white gold or platinum.

These pieces were typically forged from 18-carat white gold or platinum, utilising prong or channel settings to secure central faceted gemstones alongside grain-set accent diamonds.

Authenticity is assessed through hallmarks indicating metal purity, microscopic examination of gemstone inclusions, and traditional craftsmanship techniques consistent with the mid-20th century.

A vintage cocktail ring serves as a focal point, pairing well with understated evening wear or serving as a striking contrast against minimalist everyday tailoring.

Jewellery should be cleaned periodically using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners on treated stones, and stored separately to prevent scratching.
