Vintage Diamond Solitaire Engagement Rings
A diamond solitaire is one of the most enduring ring designs ever made. In a vintage or antique solitaire, that simplicity is matched by a quality of making and a character of stone that gives each ring its own distinct personality.
Our collection includes both old cut and brilliant cut diamonds, and both have their own particular beauty. Old mine cuts and old European cuts — found in the older rings in our collection — have a deeper, warmer quality of light, their larger open facets producing a flash that feels romantic and individual. Brilliant cut diamonds, found in our more recent preloved pieces, bring a bright, crisp sparkle and a clean, timeless elegance that suits any setting.
Each of our rings is completely unique, hand picked by one of our family.

Very pretty 18ct white gold diamond half eternity ring set with a row of round brilliant cut diamonds across the front of the band, totalling approximately 0.36ct. The diamonds are claw set in a continuous line, with a plain band to the reverse. It suits use as a wedding ring, an anniversary ring, or worn alongside an engagement ring.
What is an eternity ring for?
An eternity ring is a band set with a continuous line of matching stones, usually diamonds, given as a symbol of lasting love and commitment. It is traditionally given to mark a significant moment, such as a wedding, a milestone anniversary, or the birth of a child, with the unbroken line of stones representing everlasting love. Eternity rings are worn as wedding bands, as anniversary rings, or stacked alongside an engagement ring.
What is the difference between a full and half eternity ring?
A full eternity ring is set with stones all the way around the band, while a half eternity ring, like this one, is set with stones across the front half only. A half eternity is often chosen for its comfort and practicality, as the plain section to the underside sits comfortably against the finger and allows the ring to be resized more easily.

A beautiful diamond solitaire engagement ring in 18ct gold, set with a central brilliant cut diamond of approximately 1.38ct and further diamonds to the sides, giving a total diamond weight of approximately 1.6ct. The diamonds are assessed as H colour and I1 clarity. The central brilliant cut diamond is held in a four claw setting and flanked by small diamond accents to each side, with diamond set shoulders sweeping along a crossover style band, bringing the total diamond weight to approximately 1.6 carats. The stones are assessed as H colour and I1 clarity. H colour sits within the near colourless range on the GIA scale, which means the central diamond faces up white to the eye. I1 clarity means the diamond contains some natural inclusions, which is characteristic of a stone of this size and gives it its own individual character.
What does H colour mean on a diamond?
H is a near colourless grade on the standard D to Z diamond colour scale. A diamond graded H appears white when viewed and set, with no colour visible to the eye in normal wear, which makes it a popular choice for a solitaire where the central stone is on show.
What does I1 clarity mean?
I1 is a clarity grade indicating that the diamond contains natural inclusions. In a diamond of this size, these are part of the character of the stone. Each I1 diamond is individual, and the grade is one of the reasons an older or larger natural diamond can be enjoyed at a more accessible price than a flawless equivalent.
Is this ring suitable as an engagement ring?
Yes. A single central diamond of this size in a raised setting, with diamond set shoulders, is a classic solitaire engagement ring style. It can also be worn as a solitaire dress ring.

Beautiful platinum diamond solitaire ring set with a round brilliant-cut diamond at the centre, held in a four-claw square collet setting, with further small round brilliant-cut diamonds channel-set along each shoulder of the band.

FAQs Vintage Diamond Rings
What is a vintage diamond solitaire ring?
1
A vintage diamond solitaire ring features a single diamond as the centrepiece, set in a plain or simply decorated band. Vintage solitaires are those made in an earlier era — typically anything from the Victorian period through to pieces from the last few decades that have been previously owned and loved.
Are old cut diamonds different to the more modern round brilliant cut?
2
Old cut diamonds — including rose cuts, old mine cuts, and old European cuts — were shaped by hand before modern machinery existed, giving them a softer, warmer glow rather than the sharp, dazzling brilliance of a modern round brilliant. They tend to have larger facets, a higher crown, a smaller table, and a larger culet (the flat point at the base), which creates a distinctive, almost candlelit quality of light. Many people find this far more romantic and characterful. More recent pre-owned diamond rings feature the round brilliant and its variations — princess, cushion, and oval cuts — which are engineered for maximum light return and a very different kind of sparkle. We stock diamonds across all these cuts, so whether you're drawn to the romance of an old cut or the brilliance of a modern one, we can help you find the right ring.
Are vintage diamond solitaires good for engagement rings?
3
Absolutely. A vintage diamond solitaire is one of the most timeless engagement ring choices there is — a single diamond in a quality setting that will never feel dated. The added character and history of a vintage or pre-loved ring gives it something that a brand new ring can't replicate.
Can vintage diamond solitaire rings be resized?
4
Most solitaire rings can be resized, as the plain shank gives a jeweller room to work with. We are happy to advise on sizing before you buy, and in some cases can arrange resizing before the ring is sent to you.
Why buy a vintage diamond solitaire rather than a new one?
5
Every vintage solitaire is one of a kind — a ring with its own history, its own stone and its own character. Buying vintage also means no new mining and no new manufacturing, making it an inherently more sustainable choice without any compromise on beauty or quality.
Are pre-owned & vintage diamond solitaire rings more affordable than buying new?
6
Pre-owned and antique diamond rings sidestep the immediate depreciation of buying new retail, and older cuts such as old mine and old European are not currently subject to the same premium as modern round brilliants. That said, prices vary considerably depending on era, quality, provenance, and condition. We stock pieces at a wide range of price points and are always happy to help you find something that suits both your taste and your budget.
