Lab Grown Diamond Prices UK
Lab grown diamonds typically cost 60–85% less than equivalent mined diamonds. Exactly how much you pay depends on the four Cs — carat, cut, colour and clarity — just as with a mined stone. The table below shows typical UK price ranges for loose lab grown diamonds at common carat weights, updated from live trade pricing.
| Carat Weight | From (GBP) | Typical Price Range (GBP) |
|---|---|---|
| 0.50 ct | £137 | £137 – £868 |
| 1.00 ct | £187 | £187 – £6,232 |
| 1.50 ct | £227 | £227 – £9,230 |
| 2.00 ct | £342 | £342 – £16,384 |
| 3.00 ct | £479 | £479 – £35,046 |
What drives the price
The single biggest factor is carat weight, but cut quality and clarity grade move the price significantly within any weight. A well-cut 1ct lab grown diamond with a high clarity grade can cost more than a larger stone with visible inclusions. Use the filters above to compare certified stones by price and specification side by side.
