18ct yellow gold Asscher cut trilogy (3 stone) engagement rings, handmade to order by our family workshop in the Cotswolds and set with a diamond you choose yourself. The Asscher cut is a square step-cut diamond with cut corners, much loved in the Art Deco era. A trilogy ring sets three diamonds side by side, often said to stand for your past, present and future.
The Asscher cut diamond
The Asscher is the square cousin of the emerald cut. Its deep step facets and cut corners draw the eye into the centre of the stone, giving a hypnotic, windmill-like pattern. First cut in 1902, it is the classic Art Deco diamond. The side stones are matched to the Asscher 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 18ct yellow gold?
18ct yellow gold is 75% pure gold, with the deep, warm colour people picture when they think of a gold ring. It is not plated, so the colour never fades. Some of our yellow gold designs hold the diamond in a white platinum head, so the stone looks as white as possible while the band stays golden. Yellow gold also flatters a slightly warmer diamond, so a stone in the H to J colour range can look just as good as a pricier, whiter one. For a lower price, see our 9ct yellow gold engagement rings.
Choosing your Asscher diamond
Like the emerald cut, the Asscher shows its clarity, so choose VS2 or better. Look for a ratio between 1.00 and 1.05 for a true square. A G or H colour keeps the step facets crisp and bright.

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
Both are step cuts with cut corners. The Asscher is square, with deeper facets that draw the eye to the centre; the emerald cut is longer, with a calmer, more open look.
Yes. The side stones are chosen to suit the size and colour of your centre diamond, so the three look balanced together.
Yellow gold reflects a little warmth into the diamond, so a near-colourless stone in the H to J range looks just as good as a whiter, more expensive one. If you want an icy white stone, choose a design with a platinum head.
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.
