Natural Diamonds

A natural diamond is a record of deep time. It formed roughly 150 kilometres below the earth's surface, where extreme heat and pressure crystallised pure carbon over hundreds of millions, sometimes billions, of years, before volcanic activity carried it toward the surface. That rarity, and that long journey, are part of what a natural stone carries onto the hand.

What makes a natural diamond valuable

Value rests on rarity and the four Cs. Cut governs how much light the stone returns and is the quality we protect first; colour, clarity and carat weight describe its purity and size. A larger, well-cut, near-colourless stone with few inclusions is rarer, and priced accordingly. Our guide to the 4Cs of diamonds explains how to balance the four against your budget.

Sourcing and ethics

Our diamonds are sourced through established suppliers operating under the Kimberley Process, and we seek documented provenance and traceability wherever it is available. If a documented origin matters to you, tell us at the outset and we will source to it. Recycled and heirloom stones are a further responsible route, and we are glad to reset a family diamond into something new.

Certification you can verify

GIA or IGI certification is available on every centre stone, documenting cut, colour, clarity and carat weight so you can compare like with like and know exactly what you own. Each certificate is verifiable online, and the finished piece is hallmarked at the London Assay Office.

Natural or lab-grown

Both are real diamonds, graded the same way. A natural diamond carries geological rarity and holds its value better; a lab-grown diamond offers more size or quality for the same budget. There is no wrong answer, only the one that suits your priorities, and we will talk both through with you. Settings start from £800 and complete bespoke engagement rings from £1,500.
