This Edwardian cluster ring dates from circa 1900 and is manufactured from 18k yellow gold. The piece centers on a rectangular cushion-cut blue sapphire held in four yellow gold claws, displaying a rich, transparent blue shade. Encircling the central stone is a halo of eight chunky old mine cut diamonds, complemented by two additional old mine cut diamonds set into the shoulders of the band. The ring features a pierced open-work gallery beneath the cluster head and polished yellow gold shoulders tapering down to a smooth, uniform band. The head of the ring measures 1.44 cm by 1.33 cm and sits 0.64 cm from the finger, with a total weight of 4.75 grams. Suitable for daily wear on the hand, this item integrates seamlessly into modern jewellery collections as a statement piece for special occasions or everyday accessorising.

FAQs

An Edwardian sapphire cluster ring typically features a central blue gemstone framed by a halo of diamonds set in precious metals such as gold or platinum. Produced around the turn of the twentieth century, these designs emphasise symmetry, refined claw settings, and delicate geometric arrangements.

Rings from this era commonly incorporated yellow gold, platinum, or silver-topped gold settings. Central natural gemstones, such as sapphires or rubies, were typically surrounded by hand-cut diamonds, including old mine cut and old European cut stones.

Authentic period rings often feature hand-cut diamonds with visible open culets, hand-crafted claw work, and slight asymmetry characteristic of hand-carved gemstones. Additionally, period hallmarks or distinct wear patterns on the band and settings help confirm authenticity.

An antique cluster ring functions as a standalone statement piece for formal wear or can be integrated into contemporary jewellery stacks. The classic combination of blue and gold complements both minimalist modern wardrobes and traditional evening wear.

Clean the setting gently using warm water, mild liquid soap, and a soft-bristled brush to remove dust from behind the stones. Avoid ultrasonic cleaners or harsh chemicals, as older settings may have delicate claws or natural gem inclusions vulnerable to stress.
