How to Choose the Best Lab-Grown Diamonds for Your Jewellery

Lab-grown diamonds are taking the jewellery world by storm.

In short: Lab-grown diamond selection priorities: (1) IGI or GIA certification (CVD/HPHT origin disclosed, laser-inscribed report number), (2) Excellent cut grade (most visible-beauty per pound), (3) F-H colour and VS1-SI1 clarity (eye-clean, max value), (4) Type IIa CVD or HPHT (purest, virtually nitrogen-free). Expect £700-£2,000 for 1ct in this spec.

With their ethical appeal, affordability, and striking similarity to natural diamonds, it's no wonder more and more people are choosing them for their most treasured pieces.

But how do you pick the best lab-grown diamonds for your jewellery? Whether you’re designing an engagement ring, a necklace, or a pair of earrings, this guide will walk you through everything you need to know to make the right choice.

What Are Lab-Grown Diamonds?

Lab-grown diamonds, also known as synthetic or man-made diamonds, are real diamonds that are created in a laboratory rather than being mined from the earth.

They have the same chemical and physical properties as natural diamonds, meaning they are just as durable and beautiful.

There are two main methods used to create lab-grown diamonds: Chemical Vapour Deposition (CVD) and High Pressure, High Temperature (HPHT).

Both methods produce diamonds that are virtually identical to mined ones.
