The Genesis of Lab-Grown Diamonds

Lab-grown diamonds are created using two primary methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both processes mimic the natural conditions under which diamonds form over billions of years, but within a controlled laboratory setting.

  • HPHT Method: This method simulates the high-pressure, high-temperature conditions found deep within the Earth’s mantle. A small diamond seed is placed in carbon, the element from which diamonds are made, and exposed to temperatures of about 1,500°C and pressures of approximately 1.5 million pounds per square inch. The carbon melts and begins to form a diamond around the starter seed. It is then carefully cooled to form a pure carbon diamond.
  • CVD Method: The CVD process involves placing a diamond seed in a sealed chamber and heating it to around 800°C. The chamber is filled with a carbon-rich gas, typically methane, which is ionized into plasma using technology similar to that of lasers or microwaves. The ionization breaks the molecular bonds of the gases, and the pure carbon adheres to the diamond seed, gradually crystallizing into a diamond.
