White Color Brilliant Fancy Cut Lab Diamonds For Ring And Necklace
Lab Grown Diamonds Description
Lab grown diamonds are also known as synthetic diamonds. So this
kind of diamond, is not naturally formed diamond, but by human to
cultivate. Artificial diamond is a kind of polycrystalline diamond
made of diamond crystals 10 to 30 nanometers in diameter. Its
molecular structure is not the complete octahedral structure of
natural diamond, but a complex structure, which will produce
phosphorescent phenomenon. Synthetic diamonds are cheaper to make
and can be made in a variety of colours.
Compared with the long history of natural diamonds, lab grown
diamonds were born in the middle of the last century. At the end of
the 18th century, The French chemist Lavoisier discovered that
diamond was a single crystal composed of carbon elements, which
provided a theoretical basis for the later generation of diamond
cultivation technology, and thus wrote the development chapter of
lab grown diamonds.
The main raw materials for diamond cultivation are graphite powder
and metal catalyst powder. In the process of diamond synthesis,
only graphite powder (carbon element) is synthesized to produce
diamond, and metal catalyst powder is only one kind of material to
promote the transformation of graphite powder into diamond. The
proportion of different raw materials directly determines the
particle size, performance and quality of the product. Generally,
the proportion of the consumption of metal catalyst powder and
graphite powder is about 1:1.

From a scientific point of view, cultivated diamonds are exactly
the same as natural diamonds, the only difference being where they
are formed.
Advantages of lab grown diamonds:
1. Lab groen diamond penetration rate is entering a stage of
accelerated growth. At present, the penetration rate of diamond
cultivation industry is 6%, and the market is expected to grow
diamond industry penetration rate is 10% this year. When the
penetration rate reaches about 10%, the industry enters the
outbreak period. It is precisely because the penetration rate of
new energy vehicles breaks through the key value of 10% that the
whole industry begins to break out.
2. Lab grown diamond is a stage of increasing demand, and
recognition is constantly improving. Lab created diamond is
constantly recognized, attracting big brands to enter, and terminal
demand is expected to accelerate growth.
3. The leading company in diamond cultivation has achieved rapid
growth. From the perspective of the three quarterly reports, the
diamond cultivation business of leading companies has achieved
rapid growth in the three quarters, with an average growth rate of
more than 100%, which is in the stage of rapid growth.
