Lab-grown diamonds are changing the jewellery game — offering the same brilliance, durability, and sparkle as natural diamonds, often at a more accessible price. But just like natural stones, not all lab-grown diamonds are created equal. So how do you know you’re getting a quality one? Here’s what to look for:
1. The 4Cs Still Matter
Lab-grown diamonds are graded using the same system as natural ones — Cut, Colour, Clarity, and Carat.
Cut determines how well the diamond sparkles. Look for Excellent or Very Good cuts.
Colour ranges from D (colourless) to Z (light yellow). The closer to D, the whiter the diamond.
Clarity reflects how many natural imperfections (or inclusions) are inside the stone. VS1-VS2 is a great balance of quality and value.
Carat is all about size — but a well-cut smaller diamond can often shine brighter than a larger one with poor cut.
2. Check the Certification
A reputable lab-grown diamond should come with a grading report from an independent lab, such as IGI (International Gemological Institute) or GIA (Gemological Institute of America). This confirms its quality and authenticity — and gives you peace of mind.
3. Ethical and Transparent Sourcing
Even with lab-grown stones, it’s important to buy from jewellers who are transparent about their sourcing and materials. Look for brands that also use recycled metals, and who offer clear information on how their diamonds are produced.
4. Look for a Strong Sparkle
A great lab-grown diamond should have that signature fire and brilliance. Check the sparkle in different lighting — under natural light, the stone should look bright, crisp, and full of life.
5. Don’t Forget Style
Once you’ve ticked off the quality boxes, it’s all about the design. From minimalist solitaires to halo settings and coloured stones, lab-grown diamonds are available in every style imaginable — and often give you more size and customisation for your budget. Lab-grown diamonds come in any cut, colour, clarity and carat you can find in natural mined stones, so ensure the shop has plenty of options for you to look at. If they say a lab-grown diamond ‘can’t’ come in your desired shape or colour, walk away.
The Bottom Line?
A high-quality lab-grown diamond should be graded, certified, and full of sparkle — just like any natural stone. With the added bonus of being more sustainable, ethical, and affordable, it’s no wonder so many are choosing lab-grown. Ready to find your perfect stone?
