Vintage 18ct Gold & Platinum Diamond Solitaire Ring – 0.25ct

A beautifully distinctive vintage diamond solitaire engagement ring, combining 18ct yellow gold, white gold and platinum in an elegant design featuring a square setting with decorative trefoil grain detailing.

At the centre sits a sparkling natural round brilliant-cut diamond, weighing approximately 0.25 carats, with an attractive G–H colour and VS or better clarity grade. The diamond is framed within a polished square setting, measuring approximately 5.5mm across, creating a striking geometric contrast with the circular brilliance of the stone.

The setting features delicate trefoil-shaped grain details, arranged around the diamond to provide an attractive vintage appearance. Small clusters of polished metal beads accentuate the corners of the square setting, while the bright white metal beautifully complements the diamond's near-colourless appearance.

One of the ring's most appealing characteristics is its unusual combination of precious metals. The slender 18ct yellow gold band gradually broadens towards the shoulders, transitioning into polished white gold before meeting the platinum diamond setting.

The shoulders feature decorative openwork detailing, adding a sense of lightness to the design while drawing attention towards the central diamond.

Measuring approximately 5.5mm across the setting, the ring tapers to a delicate 1mm band beneath the finger. With a total weight of 2.3 grams, it offers an elegant, lightweight appearance with a beautifully proportioned diamond setting.

The inside of the band is stamped 18CT, identifying the gold fineness.

Available in UK finger size I, this unusual vintage solitaire ring is an attractive choice for someone seeking an engagement ring with individual character, traditional craftsmanship and a distinctive combination of yellow and white precious metals.

A charming addition to our carefully selected collection of pre-loved diamond jewellery, with just one ring available.
