Pre-Loved Platinum Six-Claw 0.25 Round Brilliant Diamond Solitaire Engagement Ring London Hallmarked Size R

The diamond solitaire is the most enduring proposal in fine jewellery, and this pre-loved platinum example makes the case with quiet, confident beauty. A 0.25ct round brilliant diamond sits elevated in a classic six-claw setting above a clean, flat-shanked platinum band, the stone lifted into the light, held securely, and given every opportunity to do what a diamond does best. The flat shank gives this ring a distinctly architectural, contemporary quality that sets it apart from more traditional tapered styles, the clean lines of the band allowing all attention to rest on the stone above.

Platinum is the finest metal in fine jewellery; naturally white, exceptionally dense and entirely hypoallergenic, it holds a diamond more securely than any other metal and maintains its colour and finish without the need for rhodium plating. This ring is hallmarked by the London Assay Office and carries the 950 purity mark, confirmed by the leopard's head assay mark and the platinum fineness symbol, meaning 95% pure platinum throughout. Yes, this is real platinum and a real natural diamond, maker-marked AT LO with the diamond weight of 0.25ct stamped alongside the hallmarks inside the band.

At 4.54g the ring has the characteristic satisfying weight of platinum on the finger,  noticeably more substantial than an equivalent white gold ring, the density of the metal communicating quality immediately. The six-claw setting elevates the diamond beautifully, allowing maximum light to enter the stone from all angles while holding it with the security that platinum's strength provides. It arrives in excellent condition, the diamond bright and secure, the platinum clean and well preserved throughout.

Pre-loved and ready for a new chapter, this platinum diamond solitaire is the kind of ring that never goes out of style. Whether it becomes a proposal ring, a meaningful gift or a quietly luxurious treat for yourself, it arrives beautifully gift wrapped and ready to make a moment.

FAQ:

Is this real platinum? Yes. This ring carries the 950 platinum hallmark confirmed by the London Assay Office leopard's head mark, meaning it is 95% pure platinum, the standard for fine platinum jewellery.

Is the diamond real? Yes, the centre stone is a natural round brilliant diamond of 0.25ct, confirmed by the maker's stamp inside the band. It is not a lab-grown, synthetic or simulated stone.

Is this ring second hand? Yes, this is a pre-loved platinum diamond solitaire, previously owned and offered in excellent condition. It is ready to wear immediately.

What is the difference between platinum and white gold? Platinum is naturally white, denser and more durable than white gold, and does not require rhodium plating to maintain its colour. A platinum ring feels noticeably heavier than an equivalent white gold ring; a weight that reflects both the density of the metal and its exceptional quality and value as a material.
