Lab Grown Diamonds Description
Cultured diamond refers to man-made diamond.
Synthetic diamond is a kind of polycrystalline diamond which is
polymerized from diamond crystals 10 to 30 nanometers in diameter.
The molecular structure of lab grown diamond is not the complete
octahedral structure of natural diamond but a complex structure,
which will produce phosphorescence phenomenon.
The molecular structure of artificial diamond is not the complete
octahedral structure of natural diamond but a complex structure,
which will produce phosphorescence phenomenon. With the maturity of
lab grown diamonds production technology, its low cost, and can
produce a variety of colors of diamonds and in the jewelry market.

From a scientific point of view, they have the same physical
composition, chemical properties, optical characteristics, even the
authoritative gem appraisal agency has certified, of course, is the
same, if there is anything different between the two, it is only
the place of birth is different. For example, all people are born
differently. Why look down upon others?
There is natural diamond is but a serious damage to the earth's
surface bad environment, the cruel labor exploitation of the people
of backward Countries in Africa, the endless harm caused by armed
conflict, and finally the expensive stone monopolized by the
diamond company marketing, and the cultivation of diamond is the
light of human wisdom, the beauty created by science and
technology.
Natural mining diamond contains impurities, in fact, color, purity
is not much, so high grade can sell sky-high prices, but the basic
cultivation drill is 2a type, is the top2% of the advanced category
of diamond, cultivation drill cost is several times lower than
natural diamond.
