This Victorian solitaire ring is a vintage piece made of 18ct yellow gold with a white gold setting and a diamond. The design displays an old cushion cut natural diamond held in multiple white metal claws, a tapered yellow gold band, and openwork detail on the shoulders. The central stone measures 7.23 x 6.36 x 4.10mm, and the ring is size M 1/2 in the UK or 6.5 in the US. Appropriate for wear as an engagement ring or as an addition to a fine jewellery collection, the ring suits formal occasions or daily use. It is worn on the hand, combining the polished finish of the yellow gold band with the faceted texture of the diamond.

FAQs

An old cushion cut diamond is an antique gemstone cut featuring a square or rectangular outline with rounded corners, a steep crown, small table facet, and an open culet.

This solitaire ring is crafted with an 18ct yellow gold shank paired with multi-prong white metal claw settings to hold the primary diamond.

Authentic old cut diamonds display hand-faceted geometric proportions, deeper pavilions, and visible culets under magnification, alongside official purity hallmarks stamped inside the band.

A vintage diamond solitaire can be worn on its own as a classic statement ring or stacked alongside slim contemporary gold bands for a multi-textured look.

Maintain the ring by soaking it in warm water with mild detergent, brushing around the claws with a soft toothbrush, and having a jeweller inspect the settings periodically.
