What Are Lab-Grown Diamonds?

Lab-grown diamonds are real diamonds, created under controlled laboratory conditions that replicate the natural diamond formation process. While natural diamonds form over billions of years under intense heat and pressure, lab-grown diamonds are produced using two advanced methods: High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD). The HPHT method mimics the Earth's conditions, while CVD involves sealing a carbon-rich gas inside a chamber, heating it to over 900°C, and using a microwave beam to separate carbon atoms, which then bond to a diamond ‘seed’—a thin square of diamond that acts as a template for crystal growth. The result? A diamond that is chemically, physically, and optically identical to one found in nature.

Are Lab-Grown Diamonds Real?

Absolutely. Lab-grown diamonds are 100% real diamonds, with the same chemical composition, brilliance, and durability as natural diamonds. The only difference is their origin. Think of it like comparing ice from the Arctic to ice from your freezer—both are made of the same substance, just formed in different environments.

Should I Buy a Lab-Grown Diamond?

Lab-grown diamonds are a brilliant choice for many reasons. They offer exceptional beauty and quality at a more cost-effective price, allowing you to invest in a larger or higher-grade diamond for the same budget. Unlike stones such as cubic zirconia, lab-grown diamonds are not imitations—they are real diamonds. The only difference is their provenance. While natural diamonds remain a traditional favourite, lab-grown diamonds are rapidly increasing in popularity as an ethical and budget-friendly alternative.

Are Lab-Grown Diamonds Sustainable?

Lab-grown diamonds are a more sustainable choice compared to mined diamonds. While their creation does require energy, their environmental impact is significantly lower, as they avoid the land disruption and extensive mining processes associated with natural diamonds.

What Should I Consider When Buying a Lab-Grown Diamond?

Whether choosing a natural or lab-grown diamond, start by determining your budget and then consider the 4Cs—Cut, Colour, Clarity, and Carat. The priority order of these factors can vary based on the diamond shape and even the metal it's set in. Our diamond guides and guide to diamond shapes are tools designed to help you make an informed decision, and our team is always available to assist you with any questions.

What Is the Difference Between Lab-Grown and Natural Diamonds?

The only fundamental difference between lab-grown and natural diamonds is how they are formed. Physically, chemically, and optically, they are identical—offering the same fire, scintillation, and sparkle. However, natural diamonds are rarer due to their geological formation, which is reflected in their price.
