How are Lab Grown Diamonds made?
There are two common methods for lab diamond creation and growing, High Pressure High Temperature (HPHT) and CVD (Chemical Vapor Deposition). CVD is a newer technology and the preferred process to produce a quality, genuine diamond.
Growing these diamonds requires a unique and innovative process that starts with a thin ‘seed’ diamond placed inside a chamber and subjected to high temperatures. Then, a carbon-rich gas mixture is introduced to the chamber. The gases are ionized to break down their molecular bonds, allowing the pure carbon to attach itself to the diamond seed. As the carbon builds up, it forms atomic bonds with the seed diamond, resulting in the growth of a new, larger diamond — identical to diamonds found in nature.
