Lab Grown Diamonds: Your Questions Answered
One of the questions we get asked most often is whether we stock laboratory grown diamonds. The answer is yes, we do! To meet increasing customer demand, we’ve expanded our range to include a carefully selected selection of lab grown diamonds, stocked separately from our natural diamonds.
Whether you’re already familiar with lab grown diamonds or just after some background, this Q&A covers the key things you need to know.
What lab grown diamonds do you stock?
We offer a wide range of lab grown diamonds in various shapes and sizes — from small melee all the way up to 5 carats and beyond. Our lab grown diamonds are primarily top quality, typically in the D to F colour range and VS clarity or better. We also stock fancy coloured lab grown diamonds for those looking for something a bit different.
What are the differences between lab grown and natural diamonds?
The key difference lies in how these diamonds are created. Here are the main points to consider:
Manufacturing
Lab grown diamonds form in a controlled laboratory environment through advanced methods such as HPHT (high-pressure high-temperature) or CVD (chemical vapour deposition). In contrast, natural diamonds develop naturally over millions of years beneath the Earth's surface before being mined.
Composition
Both lab grown and natural diamonds share the same chemical composition and crystal structure.
Value
Since lab grown diamonds are produced on demand, they tend to be more widely available. Natural diamonds, however, come from finite sources in the earth. This difference means lab grown diamonds usually cost less for the equivalent size and quality but are not likely to retain their value as well over time, in comparison to natural diamonds.
How can I be sure a diamond isn’t a lab grown one sold as natural?
We take honesty and transparency very seriously. Every diamond you buy from us—whether natural or lab grown—is clearly identified. To maintain this, we test and segregate our stock carefully, with strict processes in place to manage any potential points of contamination within our offices.
Both our London and Birmingham locations are equipped with Yehuda 'Sherlock Holmes' synthetic diamond detectors, designed specifically to identify lab grown diamonds. We also follow a comprehensive product security policy, which outlines these measures in detail.
Are lab grown diamonds ethical?
All the diamonds we stock, whether natural or lab grown, come from trusted suppliers who meet strict ethical standards. As members of the Responsible Jewellery Council, we’re committed to responsible sourcing and trading, ensuring our products align with the latest industry guidelines. You can learn more about our approach in our Responsible Business Practices policy on our website.
What are the benefits of buying lab grown diamonds?
One of the biggest advantages of lab grown diamonds is their cost-effectiveness. Because they’re created in a lab, they’re generally more available and come at a lower price point compared to natural diamonds.
If you’re after a larger stone for less, lab grown diamonds can offer excellent value. Plus, many of the ones we stock are top quality—mostly D-F colour and VS clarity or better—so you don’t have to compromise on appearance.
Choosing between natural and lab grown diamonds is a personal decision. We encourage you to do your own research to understand which option aligns best with your values and needs, including the ethical considerations involved.
