Why a trilogy ring?

A trilogy, or 3 stone, ring sets a centre diamond between two smaller side stones. It gives a wider, fuller look across the finger than a solitaire, and the three stones are often said to stand for your past, present and future together.

The cushion cut diamond

The cushion cut is a square or slightly long diamond with softly rounded corners, like a pillow. Its larger facets give big, bold flashes of light, with a warm, vintage feel that goes back over two hundred years.

Choosing your cushion diamond

Our diamond search splits cushions by shape: square cushions have a ratio up to 1.08, and elongated cushions start at 1.15. Cushions can hold a little colour in their corners, so G to H is a good colour choice, with SI1 or better clarity.

Platinum or gold?

Platinum is naturally white, hard-wearing and the most secure choice for the claws that hold your diamond. 18ct white, yellow and rose gold cost a little less, and 9ct gold less again. Shop by metal: platinum, 18ct white gold, 18ct yellow gold or 18ct rose gold.

Choose your own diamond

Every ring is set with a centre diamond you choose yourself, natural or lab-grown, from our live stock. Each stone has its grading report, and the ring page shows the finished price before you buy.
