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. The side stones are matched to the cushion centre diamond so the three sit in proportion.
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.
Why platinum?
We use 950 platinum, hallmarked in the UK. It is about 95% pure, so it is naturally white all the way through and never needs re-plating. It is heavier than gold and very hard-wearing: rather than wearing away, the metal moves over time and takes on a soft satin look, which a quick polish brings back to a high shine. It is also the best choice if you have sensitive skin.
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.
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.

Frequently Asked Questions
It is down to taste. A square cushion (ratio up to 1.08) gives a classic, soft look; an elongated cushion (1.15 and above) looks larger face up and lengthens the finger. You can search for either.
Yes. The side stones are chosen to suit the size and colour of your centre diamond, so the three look balanced together.
All precious metals mark with wear. Platinum moves rather than wearing away, so it keeps its weight and holds the diamond securely. Over time it takes on a soft satin finish, and we can polish it back to a bright shine whenever you like.
Yes. Every ring can be set with a natural or lab-grown diamond from our live stock. Both are real diamonds; lab-grown stones cost less for the same size and grade.
