Lab grown diamonds show the same chemical and physical properties of natural diamonds. Chemically pure carbon atoms arrange themselves in a crystal structure identical to that of natural diamonds under the conditions of high pressure and temperature, which eventually forms a diamond crystal.
Apart from that, Chemical Vapor Deposition (CVD) and High Pressure-High Temperature (HPHT) are two processes that manufacturers use to arrange carbon atoms in a diamond structure. They start from a very fine seed of diamond and slowly grow layers of carbon atoms under precise conditions.
Although lab-grown diamonds are important, they are actually 100% carbon, just as natural diamonds. They form through similar processes characterized by the same chemical growth mechanisms and crystalline structure and are treated by the same optical attributes as mined diamonds; hence, they can legitimately be considered diamonds from every scientific point of view.
CVD process is carried out with a hydrocarbon gas mixture (generally methane) and hydrogen. Heating these gases generates a plasma that deposits carbon atoms onto the diamond seed for gradual development of crystal structure.
For HPHT diamonds (High Pressure High Temperature) preparation, pure sources of carbon such as graphite are combined with a metal catalyst such as iron, nickel, or cobalt. The above materials are placed in a specific condition of high pressure and temperature to convert carbon to diamond.
Indeed, lab-grown diamonds are not beacons of artificial materials in their final form. They have catalysts and gases employed during the growth process, but the ultimate product is pure carbon, composition ally identical to naturally formed diamonds.
However, there ain't any chemical difference amid lab-grown and natural diamond. They're again pure carbon atoms arranged thoroughly in the same cubic crystal structure, leaving them with identical physical and chemical properties.
Just like natural diamonds, lab grown diamonds can also contain tiny traces of some elements, such as nitrogen or boron. These minor trace elements have some influence on the color of the diamond, but do not have any effect on the chemistry of the diamond's basis carbon.
Even with lab-grown diamonds having the same atomic arrangement that naturally occurring diamonds have, they have the same Mohs hardness of 10 because they are composed of pure carbon crystal structure. Thus, their properties are also physically identical.
Chemically identical to their natural counterparts, lab diamonds cost less because a shorter time and fewer resources are needed to produce them as opposed to mining natural diamonds. This is because a controlled laboratory environment minimizes the requirement for time and resources while maintaining pure carbon disposition.
