Round HPHT Lab Grown Diamonds 2ct 3ct 4ct DEF Color VVS VS SI
Purity For Loose Diamonds
Lab Created Diamonds Description
Lab grown diamonds are also known as lab-made diamonds, synthetic
diamonds and synthetic diamonds. There are two main ways to make
lab-grown diamonds :CVD and HPHT.
Physical, chemical and optical properties of the same, so
laboratory cultivation of diamond is true or false? Development of
the diamond industry often use analogy to answer this question:
laboratory cultivation of diamond and natural diamond like
greenhouse flowers and natural flowers. They are both flowers, but
they grow in different environments. Lab-grown diamonds and natural
diamonds are like ice in the refrigerator and natural ice. They're
both ice, but they formed in different environments.
Natural diamonds take millions of years to form. Before volcanic
eruptions, subsurface lava Wells from about 150 to 200 kilometers
deep can slowly cool down in the crater as the crater is often
blocked. The pure carbon material pressure is 4.5 * 10 ^ 6 ~ 9 pa.
When the temperature dropped to 1000 ~ 1250 ℃, the natural diamond
crystal formation. Only a few places deep in the earth have the
physical and chemical conditions to form diamonds.
However, in the production of natural diamond growing conditions in
nature can now be simulated in the laboratory, the use of high
temperature and high pressure (HPHT) or chemical vapor deposition
(CVD) techniques, in just a few weeks can produce laboratory
production of gem grade diamond.

Characteristics Of Lab Created Diamonds
Lab grown diamonds in the chemical, optical and structure are the
same as the mining of diamonds. What does that mean?
| The Difference Between Lab Diamond And Natural Diamond |
| Attribute | Lab-Created Diamonds | Natural diamond | Distinction |

From a scientific point of view, synthetic diamond and natural
diamond exactly the same, the only difference is that the formation
of their location.
