How are Lab Grown Diamonds Created?
Chemical Vapor Deposition(CVD), also known as lab diamonds, was developed in the 1980’s and it all began with a small diamond seed.
The seed is placed in a sealed chamber and heated to around 800 degrees Celsius (that’s ~1472 degrees Fahrenheit!)
The chamber is filled with a carbon rich-gas, usually methane and hydrogen, then ionized into plasma using technology similar to a microwave.
The ionization breaks the molecular bonds allowing the pure carbon to attach itself to the diamond seed to form atomic bonds, resulting in the growth of a new, larger diamond.
