What Is A Lab-Grown Diamond?
A lab-created diamond is “grown” in highly controlled laboratory environments using advanced technological processes that replicates the natural diamond growing process. The result is a Lab grown diamond that is chemically, physically, and optically the same as those grown beneath the Earth’s surface. The only difference between the two is its origin. These lab created diamonds consist of actual carbon atoms arranged in the characteristic diamond crystal structure.
HOW ARE LAB-CREATED DIAMONDS GROWN?
Lab created diamonds are grown from the tiny carbon diamond seeds of pre-existing diamonds. These diamond seeds are now placed in the diamond growth chamber where either extreme pressure and heat or a special deposition process known as CVD. 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. The cubic shaped rough are removed from the chamber and the stone is then cut to perfection and the diamond is added to a ring setting.
HOW ARE LAB-CREATED DIAMONDS CERTIFIED AND GRADED?
Lab-created diamonds are graded and certified using the same process as mined diamonds. They receive the same grading reports from independent gemological organizations on the 4Cs: Cut, Color, Clarity, and Carat Weight. This process is designed to provide each diamond with an unbiased grade. Some of the most popular diamond certification labs are:
Gemological Institute of America (GIA)
International Gemological Institute (IGI)
Gemological Science International (GSI)
