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.
