Lab Grown Loose Diamonds Description
Lab diamonds are diamonds that are grown in a lab using a machine. Lab-grown diamonds are polished and cut to be indistinguishable from natural diamonds. Laboratory production of diamond and natural diamond is a real diamond. The main chemical component of lab-produced and natural diamonds is carbon.
At present, the high temperature and high pressure method and the chemical vapor deposition method is two main methods of diamond preparation laboratory.
Laboratory diamond forming machine can produce laboratory diamond through high temperature, high pressure and CVD technology. However, due to high temperature and high pressure, and chemical vapor deposition of diamond production machine and technology, people can be high temperature and high pressure, and chemical vapor deposition diamond with lab.
Basically, synthetic diamond and natural diamond and natural diamond has essentially the same physical properties, chemical composition and crystal structure. But it cannot be called a fake diamond, diamond on the train track "growth" and the natural diamond is different. The other is to mimic the growing conditions of natural diamonds and grow within a few months.

Natural diamond mines will be exhausted, and the main mineral resources still have more than ten years of service life. Natural diamond supply on the market will gradually by planting a diamond. So there is a big market for growing diamonds. In addition, the application of CVD diamond in civil industry will gradually mature and develop in recent years. The demand for jewelry and diamonds is 10 to 100 times higher.
