LAB Grown Diamonds
Lab-grown diamonds are real diamonds created in controlled laboratory environments using technology that recreates the conditions under which natural diamonds form.
They have the same crystal structure and the same optical and chemical properties as natural diamonds. The main difference is their origin.
How Lab-Grown Diamonds Are Created
Lab-grown diamonds are created using one of two main methods.
High Pressure High Temperature — this method recreates the intense heat and pressure conditions found deep within the Earth, transforming a diamond seed into a full crystal.
Chemical Vapour Deposition — this method grows a diamond crystal layer by layer inside a controlled environment, gradually building up the stone from a thin diamond seed.
Are Lab-Grown Diamonds Real Diamonds?
Yes. Lab-grown diamonds are real diamonds — not imitations or diamond simulants such as cubic zirconia. They share the same basic physical, chemical and optical properties as natural diamonds.
The difference is in how and where they are formed: natural diamonds form within the Earth, while lab-grown diamonds are created in a controlled laboratory environment.
Lab-Grown Diamond Grading and Certification
Like natural diamonds, lab-grown diamonds can be independently graded. IGI is widely used for lab-grown diamond grading, though other recognised laboratories may also grade lab-grown diamonds.
These reports assess the same core characteristics — cut, colour, clarity and carat weight — so you can understand exactly what you are purchasing.
Why Choose a Lab-Grown Diamond?
Lab-grown diamonds are chosen for a number of reasons, particularly by clients focused on size and specification.
Accessible Pricing
Generally more accessible pricing for a comparable size and specification.
Greater Size for Budget
The option to choose a larger diamond within the same budget.
Modern Origin
Created using advanced, controlled technology.
Same Diamond Properties
Identical physical, chemical and optical characteristics to natural diamonds.
Specification-Focused Choice
A strong option for clients prioritising size, value and specification.
Choosing the Right Lab-Grown Diamond
As with natural diamonds, the right lab-grown diamond depends on cut, colour, clarity, carat, shape, proportions and your overall ring design.
A consultation with our team can help you compare different sizes and specifications to find the right fit for your budget and style.
