Whether you are searching for an engagement ring, a pair of diamond earrings or a timeless pendant, you may have noticed the term “lab grown diamond” appearing more frequently.
As their popularity continues to rise, so do the questions. What exactly is a lab grown diamond, and how does it compare to a natural one?
In this guide, we explain the key differences and similarities, helping you make a confident and informed decision.
What is a Lab Grown Diamond?
A lab grown diamond is a real diamond, created in a controlled laboratory environment rather than formed naturally within the earth.
Using advanced techniques that replicate the natural conditions in which diamonds develop, including pressure, temperature and chemical vapour deposition, lab grown diamonds are formed from 100% crystallised carbon. The result is chemically, physically and visually identical to a natural diamond.
It is important to distinguish lab grown diamonds from simulants such as cubic zirconia or moissanite. These are entirely different materials, whereas lab grown diamonds are, quite simply, diamonds.
Why Choose a Lab Grown Diamond?
One of the most significant advantages of a lab grown diamond is value.
As they can be created in a controlled setting, they are typically more accessible than natural diamonds. This often allows you to choose a larger carat weight or higher specification stone while staying within your budget.
At Browns Family Jewellers, our lab grown diamonds are carefully selected to meet exceptional standards, typically within the DEF colour range and VS+ clarity for outstanding brilliance. All lab grown engagement rings are certified by IGI, a globally recognised authority.

Which Should You Choose?
The decision ultimately comes down to personal preference.
If you are looking to maximise size or specification within your budget, a lab grown diamond offers excellent value. If you are drawn to the rarity and natural origin of a stone formed over millions of years, a natural diamond may feel more meaningful.
There is no right or wrong choice, only what feels right for you.
