A lab grown diamond is exactly what it sounds like: a diamond created in a lab rather than deep within the Earth. But don’t let that fool you. Lab diamonds are real diamonds. They have the same sparkle, composition, and durability as natural ones formed underground over millions of years.

Lab grown diamonds are made using advanced technology to simulate the process of natural diamond formation. There are two main methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). HPHT simulates conditions found deep beneath the Earth by applying tremendous pressure and heat to carbon. CVD heats gas mixtures to create plasma that deposits carbon atoms onto a diamond crystal.

The only difference between lab grown and natural diamonds is their origin. Natural diamonds are formed deep below the Earth’s surface over billions of years, while lab grown diamonds are created in a laboratory. Despite their different origins, both lab and natural diamonds are identical in chemical composition and physical appearance.
