Solitaire Engagement Rings: A Guide
One diamond, all the attention. The solitaire is the timeless classic — here's why it endures, the prong options, and how to choose yours.
Quick answer
A solitaire is an engagement ring with a single centre diamond and no side stones. It's the most classic, timeless style: nothing distracts from the diamond, it suits every shape, and it pairs with almost any wedding band. It also lets you put more of the budget into the centre stone. Made to order in solid 9, 14 or 18ct gold, with natural diamonds graded by GIA or HRD and lab-grown by IGI.
What is a solitaire?
A solitaire is defined by one thing: a single centre diamond, held on a band, with no accent stones around or beside it. That simplicity is exactly why it has stayed the most popular engagement ring style for generations — it's elegant, uncomplicated and puts the diamond centre stage. The band can be plain or, if you'd like a little more sparkle, set with small diamonds (see our solitaire with a diamond-set band).
Why choose a solitaire?
- Timeless. A classic look that never dates.
- Lets the diamond lead. Nothing competes with the centre stone.
- Works with any shape. Round, oval, emerald, pear — all suit a solitaire.
- Pairs easily. Sits well with almost any wedding band.
- Focuses the budget. More of your budget goes into the centre diamond.
Prongs: four vs six
The centre stone is usually held by claws (prongs). A four-prong setting shows more of the diamond and gives a squarer, more modern look; a six-prong setting holds the stone more securely and gives a rounder, classic look, often making a round diamond appear a touch larger. Both are excellent — it's a balance of maximum visibility (four) versus maximum security (six). We'll advise based on your stone and lifestyle.
Which shapes suit a solitaire?
Every shape works beautifully as a solitaire — that's part of its appeal. A round brilliant is the timeless choice; ovals and cushions look soft and generous; emerald and Asscher look clean and architectural; pear and marquise look distinctive. See the diamond shapes guide to choose, or compare a solitaire with a halo if you'd like extra sparkle and size — you can browse our halo and double halo rings to see the difference in solid gold.
Metal and diamonds
Every solitaire is made in solid 9ct, 14ct or 18ct gold — never plated — and qualifying pieces are UK hallmarked under the Hallmarking Act 1973. Choose natural or lab-grown diamonds to suit your budget — natural diamonds independently graded by GIA or HRD, lab-grown by IGI. Each ring is made to your size and specification, typically within 14 days, or created as a fully bespoke design.

Frequently asked questions
What is a solitaire engagement ring?
A solitaire is an engagement ring with a single centre diamond and no side stones. Its simplicity keeps all the attention on the diamond, which is why it's the most classic style.
Is a solitaire cheaper than a halo or three-stone ring?
Often the setting itself uses fewer diamonds, so more of the budget goes into the centre stone. The overall price depends on the centre diamond you choose.
Should I choose four or six prongs?
Four prongs show more of the diamond and look modern; six prongs hold the stone more securely and look classic, and can make a round diamond appear slightly larger. Both are secure when well made.
Which diamond shape is best for a solitaire?
Any shape works. Round is the timeless choice, but oval, cushion, emerald, pear and others all look beautiful as a solitaire — it comes down to your taste.
Are solitaire rings made to my size?
Yes. Every ring is made to order in your size and specification in solid 9, 14 or 18ct gold. Natural diamonds are independently graded by GIA or HRD, lab-grown by IGI. Bespoke designs are also available.
