Natural diamonds are formed 150–200km below the Earth's surface under extreme heat and pressure over 1–3 billion years. Each natural diamond is unique — a one-of-a-kind creation of nature. For those who value rarity, tradition, and the knowledge that their diamond is a geological marvel billions of years in the making, a natural diamond is the ultimate choice.

The marquise cut features a distinctive elongated shape with pointed ends, offering the largest face-up area of any diamond shape for its carat weight. Its boat-like silhouette creates a dramatic, regal presence on the finger and makes the stone appear significantly larger than other shapes of the same weight.

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.
