Lab grown diamonds are commonly referred to as manmade diamonds or as
CVD diamonds. Lab created diamonds have been around since the 1940s.
Earlier, lab diamonds were manufactured for industrial applications. It was
only in the 1980s that gem-quality lab grown diamonds became commercially
available. Over time, the quality of these diamonds has improved extensively.
Today, you can’t tell the difference between grown diamonds and mined
diamonds unless you get an expert to look at them under a microscope.
As the name suggests, these diamonds are lab grown and are equipped to
mimic the natural circumstances under which diamonds are formed in nature.
There are two ways in which lab grown diamonds are created.
CVD process for lab grown diamonds - CVD stands for Chemical Vapour
Deposition. The CVD process utilizes carbon gasses in a contained
chamber. Carbon gasses are heated until they separate carbon atoms
within the gas. These tiny carbon atoms build up in layers resulting in a
rough diamond crystal. It takes six to ten weeks for this process.
In short, In the CVD method, a diamond seed is grown by microwave plasma
technology in a highly-controlled environment.
HPHT process for lab grown diamonds - On the other hand, in the HPHT
method, a pure solid carbon source is put under high pressure and high
temperature. In the presence of a catalyst, the pressurized and heated
carbon is crystallized into a diamond.
Either way, the result is an enigmatic lab grown diamond. At Classic Grown
Diamonds, we use the best of technology to make sure that every lab grown
diamond we manufacture is 100% pure and sustainable at the same time.
