Our lab diamonds

Our lab grown diamonds are, as the name suggests, created in a lab. And despite common misconceptions, they aren't diamond imitations. They are legitimate diamonds chemically indistinguishable from diamonds extracted from mines.

Using a process called chemical vapor deposition (CVD) small fragments of natural diamonds are added to a vacuum chamber. Methane and hydrogen is then introduced to the chamber and superheated to form a carbon-rich plasma. This plasma then attaches itself to the diamond seed in layers over the course of a few weeks, eventually forming a fully fledged diamond.

Why lab diamond rings are the ethical choice

Lab diamonds require a tremendous amount of energy to be made, but despite this they still have a carbon footprint roughly 20% that of mined diamonds.

One of the biggest ethical advantages of lab diamonds is that you can be sure they are 'conflict free' and don't involve labour exploitation. 99% of mined diamonds in circulation can't make that claim.

Additionally, there is no direct environmental destruction from mining activity.
