Solitaire setting
By Diamond BrosUpdated 4 min read
What is a solitaire engagement ring?
GIA describes the solitaire style as a single centre gemstone with little or no additional decoration. There is no halo, no side stones and no competing detail, so the diamond carries the ring.
The stone is usually held in prongs: narrow strips of metal that rise from the base of the setting and bend over the edge of the stone. GIA calls the prong setting one of the most widely used engagement ring settings because it holds a stone securely while letting plenty of light in.
Should a solitaire have four prongs or six?
Most round brilliant rings use four or six prongs, depending on the size of the stone. The choice changes the look:
- Four prongs can make the stone look slightly squarer.
- Six prongs tend to emphasize the round outline of a round brilliant.
Other shapes call for their own prong layouts, such as a protected point on a pear or V-shaped prongs on a marquise. Whichever count you choose, each prong is a place where the stone is held and also a place where metal wears. Prongs may need re-tipping, which means rebuilding worn tips with new metal, and stones may need tightening. Ask the jeweller to show you the prong tips up close, and how they would be repaired.
Plain band, pavé band or cathedral?
The centre stone is only half the decision. The band changes how the ring looks and how it is looked after. If the ring is a surprise and the finger size is a guess, the question that matters most is how easily the band can be resized: pavé-set bands can be more difficult to resize so ask how far the stones run around the band and what the jeweller would do.
| Band | What it is | What to weigh |
|---|---|---|
| Plain | A smooth band with no stones | No band stones to keep secure or work around when the ring is resized |
| Pavé | Small diamonds set close together along the band | More sparkle; GIA says pavé may need occasional maintenance and the band can be harder to resize |
| Cathedral | Arches of metal rising from the band to support the centre setting | The arches raise the setting above the band for a more prominent look; ask how that affects the height of the ring and how a wedding band will sit |
Why is a solitaire so adaptable?
Because nothing else is set in the ring, a solitaire can be made in any diamond shape and most metals, and GIA calls the style versatile. Changing the stone, the metal or the band does not mean redesigning a frame, and you can pair it with wedding bands in several ways.
There is a trade-off. With no frame, the stone is on its own. A halo is described by GIA as something that can make the centre stone look larger, and a solitaire cannot do that. Its cut, colour and clarity have to carry the ring, so a solitaire is where it pays to look at the stone itself before you commit.
How do you look after a solitaire?
Most rings can be cleaned at home with warm water, mild soap and a soft brush, and periodic professional cleaning is recommended. It adds that open designs, including prong settings, usually benefit from periodic inspection so you catch a loose stone early. GIA gives no fixed interval, so ask your jeweller what they suggest.
If you are planning one, the design studio is a place to start with shape, prong count and metal, and a custom engagement ring can be developed from there. You can also browse engagement rings or visit a showroom to talk through prong styles.
Key takeaways
- A solitaire is a single centre stone with little or no additional decoration, most often held in prongs.
- Round brilliant rings usually use four or six prongs: four can look slightly squarer, six emphasize the round outline.
- The band can be plain, pavé or cathedral; pavé bands may be harder to resize and need occasional maintenance.
- A solitaire cannot make a stone look larger the way a halo can, so the quality of the stone matters more.
- Prongs wear: They may need re-tipping, and periodic inspection and professional cleaning are recommended.
Common questions
Can a solitaire have diamonds on the band?
Yes. The word describes the single centre stone, and a solitaire has little or no additional decoration, so a pavé or other stone-set band is common. Stones on the band change the ring's care: Pavé may need occasional maintenance and a pavé-set band can be more difficult to resize.
Is a solitaire the same as a Tiffany setting?
Not exactly. A solitaire is the general style: one centre stone. The “Tiffany Setting” is a name Tiffany & Co. uses for its own six-prong solitaire design. A six-prong solitaire from any jeweller is the same idea, but it is not a ring sold under that name.
How often should a solitaire be checked by a jeweller?
GIA recommends periodic inspection of prong settings and periodic professional cleaning, but gives no set schedule. Ask the jeweller who made or sold the ring what interval they suggest, and have the ring looked at sooner if you hear rattling or see a prong tip that looks worn, bent or lifted.
Does a solitaire suit every diamond shape?
Most shapes can be set as a solitaire, but the prongs change with the shape. Protect the point of a pear with a prong or bezel and use V-prongs on the tips of a marquise; a heart is usually set with prongs on the lobes rather than in the cleft. Tell the designer the shape first.
