Lab Grown Diamond Rings

Lab grown diamonds are real diamonds. They share the same carbon crystal structure, hardness (10 on the Mohs scale), refractive index, and brilliance as mined diamonds. The Gemological Institute of America (GIA), International Gemological Institute (IGI), and HRD Antwerp all grade lab grown diamonds using the same 4C criteria — cut, colour, clarity, and carat weight. Even trained gemologists cannot distinguish them from natural diamonds without specialised laboratory equipment.

The price difference is significant. Lab grown diamonds are typically 60–80% less expensive than equivalent natural diamonds. A 1 carat F colour VS1 clarity lab grown diamond starts from approximately £400–£600, compared to £3,000–£5,000 for an equivalent natural stone. This means a complete lab grown diamond engagement ring at MOH — setting plus diamond — starts from approximately £1,200 for a 1ct solitaire in platinum.

Quality is not compromised. Because lab grown diamonds are created in controlled conditions, they consistently achieve high clarity and colour grades. At MOH, our standard recommendation — the Perfect Balance preset — pairs F colour with VS1 clarity, delivering a diamond that faces up completely white and eye-clean in any setting. For those seeking the very best, our Most Brilliant preset offers D colour VVS1 clarity at prices that would be prohibitive with natural diamonds.

Every ring is handcrafted in Hatton Garden. MOH is based in London's historic jewellery quarter, where generations of master craftsmen have worked since the 1830s. Our workshop handles every stage of production — from CAD design to stone setting to final polish. Whether you choose a solitaire engagement ring, a full eternity band, or a personalised alphabet ring, every piece is made to order with the same care and precision.

The choice between lab grown and natural is personal. Both are real diamonds. Lab grown offers better value per carat and a smaller environmental footprint. Natural diamonds carry geological rarity and traditional prestige. At MOH, we offer both — and our complimentary consultations help you decide which is right for you. You can book a free appointment at our Hatton Garden atelier to see both options side by side.
