What Are Lab Grown Diamonds?

Lab created diamonds have the same physical properties as mined diamonds and therefore look exactly the same. It is impossible to tell the difference between the two with the naked eye.

The hardness is exactly the same as it’s the same material. A natural diamonds hardness is 10 on the MOHS scale and a lab grown diamonds hardness is also 10.

How Are Lab Grown Diamonds Made?

The two most commons ways to make Lab Grown Diamonds is either High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Essentially diamond seeds are placed into a chamber where methane and hydrogen gases stick to the seed and the diamonds carbon atom grows over the course of 3 to 4 weeks.
