Celine | 1.51ct Long Cushion Cut Lab Grown Diamond Trilogy Engagement Ring | 18ct Yellow & White Gold
A 1.51ct long cushion cut lab grown diamond, D colour, VVS2 clarity, held in a four-claw setting and flanked by two round brilliant diamonds, set in 18ct yellow and white gold.
Why this ring works
The long cushion is a softer, more romantic take on a classic shape. It has the gentle rounded corners of a cushion but a more elongated outline. The faceting holds beautiful sparkle, somewhere between the crushed-ice softness of a cushion and the open flash of a round.
A trilogy setting is one of the most meaningful designs you can choose. The three stones are often said to represent the past, present, and future, which makes it a popular choice for an engagement ring. Beyond the symbolism, the two side diamonds add width and brightness on the hand and make the centre stone feel even more substantial.
The two-tone metal is a deliberate choice. The white gold claws and accent settings keep the diamonds reading bright and icy, with no warm tone interrupting the colour, while the yellow gold band brings warmth and that classic, timeless look. You get the best of both.

A note on lab grown diamonds
A lab grown diamond is a real diamond. It's identical to a natural diamond chemically, optically, and physically. The only difference is how it formed: a natural diamond grew in the earth over billions of years, while a lab grown diamond was created in a matter of weeks under the same conditions of heat and pressure. Once they're cut and polished, only a gemmologist with specialised equipment can tell them apart.
