Lab Grown Diamonds Description
Basically speaking, lab grown diamond and natural diamond have the same physical properties, chemical composition and crystal structure as the natural diamond. It can not be called fake diamonds, but the "growth" trajectory and environment of cultivated diamonds and natural diamonds are different. One is honed over hundreds of millions of years, and the other is to simulate the growth environment of natural diamonds, which takes a few months to grow.
Lab grown diamond and the natural diamond are the same in nature, even the hardness is the same, the biggest difference is in the way of formation.
Characteristics Of Lab Grown Diamonds
There are two kinds of mass-produced diamond Deposition methods on the market: Chemical Vapor Deposition, CVD, and High Pressure High Temperature, High Temperature and High Pressure, HPHT.
① High temperature and pressure (HPHT) diamond cultivation technology: the first generation of diamond growth technology, high temperature and pressure technology completely simulates the growth process of natural diamond, reproduce the reaction of carbon layer on the ground and convert graphite into lab grown diamond;
(2) chemical vapor deposition (CVD) diamond cultivation techniques: with sand or patches to the size of the diamonds as seeds, using microwave to diamond can grow in the environment of high temperature and low pressure, adding up to 5537 ℃ in plasma reactor carbon atoms, atoms can one by one, attached on a thin piece of diamond crystals, 'growing up gradually become great lab grown diamond.

From a scientific point of view, cultivated diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
Prospects And Advantages Of Lab Grown Diamonds
Through the reflection of the major diamond traders, we can see that the diamond industry does not reject the cultivation of diamonds, but laboratory-grown diamonds and natural diamonds are still two completely different concepts. Most practitioners would like to see the industry become more regulated, which would allow consumers to better distinguish between cultured and natural diamonds and draw a relatively clear line between lab-grown and natural diamonds.
After all, lab-grown diamonds are real diamonds. Lab-produced diamonds are lab-produced "gems" that are design elements for everyday accessories in the mid-to-low market. Lab-grown diamonds are meant to be worn.
