A solitaire is the simplest engagement ring design and the most popular for the same reason: one diamond, nothing competing with it. No halo, no side stones, no pavé on the band. The focus is entirely on the centre stone.

Why solitaires endure

Fashion changes; a solitaire does not. A ring you can still wear in twenty years without it looking dated is worth more than a ring that trends one year and looks heavy the next. The solitaire is the timeless choice.

Prong count

Four-prong solitaires maximise light return. The diamond looks its biggest and sparkles the most. Six-prong solitaires (the Tiffany setting) are slightly more secure and give the ring a more traditional silhouette. Bezel-set solitaires wrap the entire girdle of the diamond in gold, which is the most secure option for active lifestyles. Six-prong is the most popular; four-prong is our recommendation for maximum sparkle.

Shape choices

Solitaires work with every shape. Round brilliant is the classic. Oval elongates the finger. Emerald cut is more understated. Pear is for someone who wants something different.

Lab-grown or natural

Lab-grown solitaire engagement rings let you go to 2-3 ct centre stones at a 1 ct natural price. The natural solitaire collection sits within our broader natural diamond engagement ring collection.

Frequently Asked Questions

Is a solitaire engagement ring out of style?

No. The solitaire is the most-bought engagement ring style in the world and has been for a century. Its simplicity is exactly why it doesn't date.

What carat size looks best in a solitaire setting?

There is no wrong answer. 1 ct is the most popular in natural; 2 ct is the most popular in lab-grown. Below 0.75 ct, a solitaire can look delicate. Consider a halo if you want the ring to read bigger.

Four-prong or six-prong. Which is better?

Four-prong shows more of the diamond and lets in more light for maximum sparkle. Six-prong is the classic 'Tiffany' look and slightly more secure. Six-prong is more common; four-prong is our recommendation for the brightest look.

How do I keep a solitaire ring secure?

Bring it in for a prong check every 2-3 years (free for life). Don't wear it to the gym. Impact with weights is the most common cause of a loose prong. If a prong ever feels rough to the touch, stop wearing the ring and bring it in.

Can the band on a solitaire have diamonds?

Yes, but then it is not technically a solitaire. It becomes a 'solitaire with pavé band' or a 'side stone setting'. We can customise any solitaire with pavé accents if you want the extra sparkle.

Are solitaires easy to resize?

Yes. Solitaires are the easiest ring style to resize because the band is uninterrupted by diamonds. First resize within 60 days is free.
