What are Lab-Grown Diamonds?


Lab Diamonds are diamonds created in a labroratory using advanced technology that replicates the natural process in which diamonds form deep within the Earth.

Just like mined diamonds, they are made of pure carbon and share the same chemical, physical, and optical properties.

Lab-grown diamonds offer a modern, ethical alternative to mined stones. They share the same brilliance, durability and beauty as natural diamonds, but with greater affordability and clarity options. This guide explains how lab diamonds are made, how they compare to natural gems, and what to consider when choosing one.

How are Lab Diamonds Made?

Two main methods are used to create them:

  • High Pressure High Temperature (HPHT): replicates the natural conditions found deep underground.
  • Chemical Vapor Deposition (CVD): Uses a carbon-rich gas to grow diamonds layer by layer. Both methods produce brilliant, durable diamonds that are visually identical to natural diamonds.

 

Why Choose Lab Diamonds?


Ethical & Sustainable: Conflict-free and environmentally conscious.

Affordable: They generally cost 30-40% less than natural diamonds of the same quality, allowing you to purchase a larger, higher-quality stone for your budget.


Quality: Since lab diamonds are made in controlled environments, there are often fewer imperfections and inclusions than many natural diamonds.

For our budget-conscious clients, we highly recommend lab diamonds, as they offer the same beauty and brilliance as natural diamonds, with no noticeable difference to the naked eye. This allows you to choose a larger carat size at a fraction of the price of a mined diamond.

The Sustainability Behind Lab-Grown Diamonds


Many people choose lab-grown diamonds for their transparent and controlled production process. Because they’re created in specialised facilities, the environmental impact can be easier to measure, and the use of renewable energy in some laboratories has further improved sustainability efforts. While sustainability can vary depending on the producer, lab-grown diamonds offer an option for those who want a gemstone with a traceable origin and a clearly defined creation process.
