Lab-grown diamonds of various colors grown by the high-pressure-and-temperature technique. A synthetic diamond or laboratory-grown diamond (LGD), also called a lab-grown diamond, [1] laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is a diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is ...
Thin needles of diamond can be made to vary their electronic band gap from the normal 5.6 eV to near zero by selective mechanical deformation. [46] High-purity diamond wafers 5 cm in diameter exhibit perfect resistance in one direction and perfect conductance in the other, creating the possibility of using them for quantum data storage.

Synthetic diamonds, also referred to as lab-grown diamonds, are created using advanced technological processes such as High-Pressure High-Temperature (HPHT) and Chemical Vapor Deposition (CVD). These methods result in diamonds that are chemically and physically identical to natural diamonds , offering the same brilliance and durability.
Gemesis created the world's largest lab-created diamond in April 2013, broke that record in November 2013, and then broke the record again in July 2014. The first was a 1.29 carat emerald cut, the second was a princess cut at 1.78 carat, [20] and the third was a 3 carat round brilliant white Type IIa diamond. [4]
Hall produced synthetic diamond in a press of his own design [2] on December 16, 1954, and showed that he and others could repeat the process following Hall's procedure, a success which led to the creation of a major supermaterials industry. Hall was one of a group of about a half dozen researchers who had focused on achieving the synthesis for ...
