A round three-stone ring symbolises past, present, and future — and the round brilliant's symmetry makes it the ideal choice for a balanced trilogy design. The three stones create a graduated, harmonious line across the finger.

The round brilliant cut features 58 precisely arranged facets mathematically optimised to maximise light return, fire, and scintillation. Accounting for over 60% of all engagement rings sold worldwide, the round brilliant is the most researched and refined diamond shape in existence. Its symmetrical silhouette offers unmatched sparkle from every angle.

The three stone (trilogy) setting features a centre diamond flanked by two smaller stones, symbolising the past, present, and future of your relationship. This meaningful design adds visual weight and interest while telling a story.

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.

Three-stone rings offer a symbolic alternative to the solitaire while delivering more total diamond weight.
