Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. They have the same crystal structure, hardness (10 on the Mohs scale), refractive index, and thermal conductivity. The only difference is their origin — grown in a controlled laboratory environment in 6–10 weeks rather than formed over billions of years. Lab-grown diamonds are typically 60–80% less expensive than equivalent natural diamonds, allowing you to choose a larger, higher-quality stone within your budget.

The radiant cut combines the elegant shape of an emerald with the brilliant-cut faceting of a round, producing exceptional fire in a rectangular or square silhouette. Its cropped corners give it a distinctive look that is both modern and versatile, while its faceting pattern hides inclusions well.

An engagement ring does not need to cost a fortune to be meaningful. Under £1,000, lab-grown diamond rings offer genuine sparkle and certified quality at an accessible price. At MOH, every ring in this range is handcrafted in Hatton Garden with the same care as our most expensive pieces.
