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. To find out more information about the process and the technology involved please visit our education hub.


Lab grown diamonds are made using specialist laboratory equipment with high pressures, high temperatures and gasses to produce a diamond.
These diamonds can be made 20 to 30 at a time and take just a few weeks in manufacturing time. They have none of the high mining costs and much fewer of the middle men that would be associated with natural diamonds.
No there isn’t. these diamonds are made using lab equipment.
Lab diamonds are all around a good choice. They are better value, they are more eco and the look the same and are just as hard as natural mined diamonds.
