Lab Created Diamonds Description
Lab diamond (artificial diamond) is a kind of diamond crystal synthesized by scientific method to simulate the crystallization conditions and growth environment of natural diamond. From the point of product attributes, lab created diamond and natural diamond is pure carbon crystal, is the same as the natural diamond is the physical, chemical and optical properties, transparency, refractive index, dispersion, etc., in brightness, luster, color, flash fire completely same as the characteristics of natural diamond jewelry, such as laboratory cultivation and natural diamonds are real diamonds.
Artificial diamonds, often referred to as lab-grown HPHT diamonds, are created by mimicking the crystallization process of natural diamonds. Natural diamond to form in the natural environment, often mixed with other elements, which makes some natural diamonds are not completely transparent, will show the specific color. For example, some diamonds have a tinge of pink, some have a tinge of blue, and some have a tinge of canary yellow. Diamonds were grown in the laboratory of high temperature and high pressure, less than natural diamond impurities, so it is more purity and transparency.
In general, high-temperature and high-pressure diamonds grown in a laboratory are little different from natural diamonds, making it difficult to tell them apart with scientific instruments. In essence, laboratory breeding without high temperature and high pressure processing of diamond and natural diamond is actually a kind of thing, but their production in a different way.
Whether HPTP diamonds or CVD diamonds, we are witnessing the maturation of their manufacturing processes.

From a scientific point of view, synthetic diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
