how are
lab-created
diamonds grown?
High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD)
what is
lab created diamonds?
A lab-created diamond is “grown” inside a lab using cutting-edge technology that replicates the natural diamond growing process.
The result is a man-made diamond that is chemically, physically, and optically the same as those grown beneath the Earth’s surface
High Pressure
High Temperature (HPHT)
HPHT diamonds are made using one of three manufacturing process: a belt press, the cubic press, and the split-sphere (BARS) press. All of these processes create an environment of extremely high pressure and temperature conducive to diamond growth
An HPHT diamond begins as a small diamond seed that is placed into carbon. Using one of the manufacturing processes above, the seed is exposed to temperatures of about 1500 degrees Celsius and pressurized to approximately 1.5 million pounds per square inch
The pure carbon melts and starts to form a diamond around the starter seed. It is then carefully cooled to form a pure carbon diamond
Chemical Vapor Deposition (CVD)
A CVD diamond begins as a thin slice of diamond seed, which is often an HPHT produced diamond. The diamond seed is placed in a sealed chamber and heated to around 800 degrees Celsius.
The chamber is filled with a carbon rich-gas, like Methane, and other gases. The gases are ionized into plasma using technology similar to that of microwaves or lasers. The ionization breaks the molecular bonds in the gases, and the pure carbon adheres to the diamond seed and slowly crystallizes.
how are
lab-grown diamonds graded and certified?
They are certified by well-known institutes such as the IGI (International Gemological Institute) and GIA(Gemological Institute of America).
The IGI became fully equipped to identify and certify synthetic diamonds in the early 1990s. The IGI is known worldwide for its quality of work
