Lab Created Diamonds Description
Cultured diamond is laboratory synthetic "real" diamond: lab
creared diamond is through modern technology in the laboratory to
simulate the growth environment of natural diamond to grow out of
the diamond, and natural diamond attributes, are real diamond. The
birth of lab created diamond can be traced back to the 1950s. There
are two main methods to produce and lab created diamonds: high
temperature and high pressure method (HPHT) and chemical
meteorological deposition (CVD). Compared with natural diamond, lab
created diamond has obvious advantages in quality (providing bigger
and more beautiful diamond), cost (the price is only one third of
natural diamond), environmental protection (lab created diamond
saves water resources, reduces land loss, carbon emissions) and
other aspects. Now lab grown diamond has obtained IGI, GIA and NGTC
national inspection certificates.
The so-called "lab created diamond", known as laboratory
cultivation diamond, also known as growth diamond, known as
synthetic diamond in the national standard. Lab grown diamond
products are comparable to natural diamond in crystal structure
integrity, transparency, refractive index, dispersion and other
aspects. As an emerging choice in diamond consumption field, lab
grown diamond products can be used to make diamond rings,
necklaces, earrings and other diamond accessories and other fashion
consumer goods.

From a scientific point of view, cultivated diamonds are exactly
the same as natural diamonds, the only difference being where they
are formed.
Lab-grown diamonds have exactly the same physical, chemical and
optical properties as natural diamonds, and have a hardness of 10.
