Lab Grown Diamonds
A diamond that is created in a lab is just as real as a natural diamond. They have the same physical and chemical properties and are grown under the same temperature and pressure conditions.
Lab grown diamonds are grown from the tiny carbon diamond seeds of pre-existing diamond. Advanced technology – either extreme pressure and heat or a special deposition process known as CVD – mimics the method of natural diamond formation, allowing them to display the same physical, chemical, and optical characteristics as natural diamonds, and exhibit the same fire, scintillation, and sparkle.
A lab grown diamond can only be distinguished from natural diamonds using specialized equipment that can detect the minor differences in trace elements and crystal growth.
Lab Grown Diamonds are grown over a very short period of time- typically two to three weeks or less. A longer growth period results in a larger crystal and better-quality crystal, however, steady heat and pressure must be maintained to ensure the formation of high-quality gem crystals.
Two crystal growth methods are used to create lab grown diamonds: HPHT and CVD.
HPHT – uses high temperatures and pressures from molten metal and diamond seed to initiate crystal formation.
CVD – uses chemical-vapor-deposition. This method produces diamonds using low pressures and high temperatures in a vacuum plasma reactor.
The same types of inclusions and imperfections present in natural diamonds can also occur in lab diamonds. If the diamond crystal grows too quickly, there can be minuscule cracks in the diamond.
There can also be small inclusions of trace elements or other growth defects that cause the diamond to be near-colorless or slightly included.
Lab crown diamonds and natural diamonds are cut and polished by the same master cutters and to the same specifications.
They are graded on the exact same criteria as natural diamonds by independent gemological laboratories that also grade natural diamonds.
We at Privée Diamonds Direct carefully handpicked our lab grown diamonds from an elite group of global growers and cutters, based on our strict quality control policies, where excellent cut and top-quality crystal, are our priority.
While originally developed in 1950, progress on the technology for single crystal growth has accelerated rapidly during the last decade. Today, groundbreaking advances in the production process, increase awareness, availability and healthy demand have transformed lab grown diamonds into valuable and meaningful alternatives to naturally mined diamonds.
