A three stone ring sets a centre diamond between two companions, a composition often read as past, present and future. The form is generous and architectural. It gives a ring real presence on the hand and, handled well, more light than a solitaire of the same centre weight. Each one we make is drawn and built for a single person.

Proportion between centre and sides

The relationship between the centre stone and its companions decides everything. A centre that reads clearly as the focal point, with sides set in measured proportion, keeps the design balanced rather than busy. Push the sides too large and the eye loses the middle. Make them too small and the ring reads as a solitaire with afterthoughts.

We model these ratios in person, so you can judge the effect at hand-scale before a single stone is set. The companions also lift the perceived size of the centre, which is one reason many clients prefer this shape to a plain solitaire.

Tapered or uniform side stones

Side stones can match the centre in cut and sit at a steady weight, or they can taper, stepping down in size to draw the eye inward. Tapered baguettes and graduated rounds give a sleek, directional line. Uniform sides feel symmetrical and classical. Both are valid, and the choice is largely one of temperament.

  • Matched rounds for a soft, even sparkle
  • Tapered baguettes for clean, linear geometry
  • Half-moons or trapezoids to hug a larger centre
  • Coloured side stones, such as sapphire, for contrast

Diamonds or coloured stones

The companions need not be diamonds. A pair of well-matched sapphires or emeralds beside a colourless centre makes a ring that is unmistakably personal. When you do choose diamonds throughout, matching the sides to the centre on colour and clarity matters more here than on most designs, because the stones sit side by side and any difference is visible. We offer both natural and laboratory-grown diamonds, each independently graded.

Width and sparkle without a halo

A three stone design widens the ring and adds fire across the finger using fewer, larger stones rather than a frame of pavé. It is the natural answer for anyone who wants scale and brilliance but finds a halo too ornate. The result is bolder in outline yet cleaner in detail.

Common questions

What do the three stones mean?

They are most often read as past, present and future, the centre marking the present moment with a companion on either side. The meaning is yours to keep or set aside. Plenty of clients simply love the proportion and the light.

How much does a three stone ring cost?

Settings start from £800 and a complete bespoke engagement ring starts from £1,500. The final figure depends on the metal, the carat weights and whether the side stones are diamonds or coloured stones. We give a clear, itemised quotation before any work begins.

Can the side stones be added later?

It is far better to plan the full composition from the start, since the shoulders and setting are built around all three stones together. If you anticipate changes, tell us early and we will design with that in mind. We work in platinum and 18ct golds.

We have designed and made fine jewellery in our own London workshop, our founder at the bench since 1999, and we would be glad to draw something for you. To begin, book a consultation at our private studio near Farringdon, or read more about our approach to bespoke engagement rings.

What do the three stones in a three-stone ring represent?

Traditionally the three stones symbolise past, present, and future, a romantic metaphor for a relationship that has grown, is flourishing, and will continue. Some clients choose to interpret them as the couple plus their children, or simply as a visual design choice. The symbolism is yours to define.

Do the three stones have to be the same shape?

Not at all. Classic three-stone designs use identical shapes (three rounds, or three ovals), but mixed-shape combinations create striking effects. Popular combinations: round centre with pear-shaped sides; oval centre with tapered baguettes; emerald centre with trillion-cut sides. Our designers help balance proportions so the stones visually harmonise.

How large should the side stones be relative to the centre?

A classical ratio is one-third to one-half the centre stone's carat weight per side stone. For a 1.50ct centre, side stones of 0.40-0.75ct each work well. Too small and the side stones look like accents; too large and they compete with the centre. We CAD-render each proposed proportion so you can see before committing.

Can I use coloured gemstones in a three-stone ring?

Yes, and a particularly elegant combination is a diamond centre flanked by two sapphires, rubies, or emeralds (or vice versa). Engagement rings with a sapphire centre and two diamond sides have a long royal heritage. Make sure the coloured stones are durable (Mohs 7.5+) for daily wear.

How much does a three-stone ring cost?

Bespoke three-stone engagement rings start from around £2,800 in 18ct gold with a 0.70ct centre and 0.30ct sides. Premium builds with 1.50ct+ centres and 0.50ct+ sides in platinum typically run £10,000 to £25,000. The three stones together carry significantly more total carat than a solitaire, so budget scales with that.
