Lab grown diamonds are chemically, physically and optically identical to natural mined diamonds. The only difference is their origin. For buyers who want exceptional diamond quality with outstanding value, a lab grown diamond engagement ring is one of the finest choices in modern fine jewellery.

Why Choose a Lab Grown Diamond Engagement Ring?

Shop by Diamond Shape

Shop by Setting Style

Choosing Your Lab Grown Diamond

Our lab grown engagement rings are available across a range of carat weights, colour grades and clarity grades. For the finest quality, look for D-E colour and VVS-VS clarity. Specific diamond details and any grading reports are listed on each individual product page. Our Hatton Garden team is available to help you choose the right diamond for your budget and style.

Lab Grown vs Natural Diamond — Which Should I Choose?

Both are real diamonds. Lab grown diamonds offer the same brilliance and durability as natural diamonds at a more accessible price point, allowing you to choose a larger stone or higher quality grade for your budget. Natural diamond engagement rings are also available at FineDiam for those who prefer a traditionally mined stone.
