Solitaire Diamond Ring Guide: Shapes, Carats and Prices in 18K Gold
Buying guide
A solitaire diamond ring has a single centre diamond on a band with no other stones competing for attention. Choose the shape first, then the carat, then natural or lab-grown, then the gold colour. Our Classic Round Diamond Ring costs AED 6,000 with a 1 ct lab-grown diamond and AED 20,000 with a 0.5 ct natural one, in 18K white, yellow or rose gold (November 2026). It is the classic engagement ring, and part of our engagement ring guide.

What is a solitaire ring?
"Solitaire" means one stone. In a solitaire ring the centre diamond sits alone on the band, so its shape, size and sparkle carry the whole design. That is why a solitaire suits almost every hand, works as an engagement ring for decades, and stacks easily with a wedding band (the «دبلة»). Rings with side stones, such as our Royale line with two pear diamonds beside the centre, are not solitaires.

Which diamond shape suits a solitaire?
All seven of our Classic shapes are made as solitaires. Each changes how large the diamond looks and how it reads on the hand.
| Shape | Look on the hand | Good to know |
|---|---|---|
| Round | The most sparkle, timeless | The reference shape for engagement rings |
| Oval | Looks larger per carat, lengthens the finger | A modern alternative to round |
| Pear | Soft and elongated, a teardrop | The lowest Classic starting price: AED 5,100 |
| Emerald | Long step-cut facets, a calm, glassy look | Shows clarity more than brilliant cuts |
| Cushion | Square with rounded corners, vintage feel | Soft and bright |
| Marquise | Long and pointed, the most spread per carat | Makes fingers look slimmer |
| Heart | Romantic and unmistakable | Best from about 1 ct, so the shape reads clearly |

|---|---|---|
| Lab-grown (CVD) | 1 ct | AED 6,000 |

What to buyClassic Round Diamond Ring, from AED 6,000Natural or lab-grown for a solitaire?
Both are real diamonds with the same crystal; a lab-grown diamond is grown in a lab instead of mined. The difference is price and rarity. At the same budget, lab-grown gives a much larger centre stone: AED 8,000 buys a 2 ct lab-grown round, while a natural 0.5 ct round is AED 20,000. Natural diamonds suit buyers who value rarity and origin. Our natural or lab-grown checklist walks through the decision.
How many carats should a solitaire be?
A solitaire has no side stones to add presence, so carat matters more than in other designs. 1 ct is a good place to start comparing; 2 ct reads clearly from across a room. Elongated shapes (oval, pear, marquise) look larger than a round of the same weight.
White, yellow or rose gold?
White gold frames the diamond in a cool tone and makes it look whiter. Yellow gold gives warmth and contrast. Rose gold is soft and modern. Every Classic solitaire comes in all three 18K colours at the same price.
