18ct Yellow Gold Emerald Cut Trilogy (3 Stone) Engagement Rings

18ct yellow gold emerald 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 emerald cut is a long, step-cut diamond with clean lines and broad flashes of light, for an elegant, Art Deco look. A trilogy ring sets three diamonds side by side, often said to stand for your past, present and future.

The emerald cut diamond

The emerald cut uses long, flat step facets instead of the brilliant facets of a round. Rather than sparkle, it gives broad flashes of light and a clear "hall of mirrors" look into the stone. Its long shape and cut corners give a quiet, elegant ring that looks larger than its weight. The side stones are matched to the emerald 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.

Choosing your emerald diamond

The open step facets show more of the inside of the stone, so clarity matters more than on a round: VS2 or better is a safe choice. A ratio of 1.30 to 1.50 gives the classic shape. The cut corners protect the stone, so it is a practical choice for everyday wear.

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.

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.
