What is lab grown diamond?
Lab created diamonds, also known as lab-grown diamonds and synthetic diamonds, are pure carbon diamonds grown in highly-controlled laboratory conditions that simulate the Earth’s natural growing process, above ground.
Most commonly used by laboratories are CHEMICAL VAPOR DEPOSITION (CVD) and HIGH-PRESSURE HIGH-TEMPERATURE (HPHT)
CHEMICAL VAPOR DEPOSITION
CVD
Chemical Vapor Deposition, or CVD, is a process used to create gem-grade diamonds as well as optics and semiconductors. The CVD process uses ultra-pure carbon-rich gasses in a controlled chamber.
Carbon based gasses, such as methane, are heated until they break apart allowing the carbon atoms within the gas to separate. These tiny carbon atoms fall onto a diamond substrate and build up layers resulting in a rough diamond crystal.
HIGH-PRESSURE HIGH-TEMPERATURE
HPHT
High-Pressure High-Temperature, or HPHT, recreates a diamond's natural growing environment found deep within the Earth.
The machines used have the ability to build up the pressure of almost 60,000 atmospheres and temperature of 2,500 degrees Celsius.
