Man Made Lab Created Diamonds Description

 

Man Made diamond is a kind of polycrystalline diamond which is polymerized from diamond crystals 10 to 30 nanometers in diameter. The molecular structure of artificial diamond is not the complete octahedral structure of natural diamond but a complex structure, which will produce phosphorescence phenomenon.

Due to the different natural environment, 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 artificial diamond production technology, its low cost, and can produce a variety of colors of diamonds and in the jewelry market. While synthetic diamonds from laboratories and factories have been around for decades, synthetic diamonds of gem-quality have only recently emerged. Synthetic diamonds were originally used for industrial purposes such as making cutting tools, but they are also used in jewelry.

Lab-grown gemstones are designed by engineers to master the chemical composition, physical properties and natural origin of natural gemstones through analysis, and to simulate the natural forming environment of natural gemstones in the laboratory so as to breed gemstones with the exact same composition and characteristics as natural gemstones.
Because of the different natural environment, the molecular structure of lab created diamonds is not the complete octahedral structure of natural diamond, but a complex structure, which will produce phosphorescence phenomenon. With the maturity of synthetic diamond production technology, its cost is low, and can be made into a variety of colors of diamonds and jewelry market. While synthetic diamonds have been produced in laboratories and factories for decades, gem-quality synthetic diamonds have only recently emerged. Originally, man-made diamonds were mainly used for industrial purposes such as making cutting tools, as well as for jewelry.

Man Made Lab Created Diamonds Introduction

 

The adoptive mother of the gia diamond is a natural diamond. It contains high purity methane. In gases such as hydrogen and nitrogen, the carbon molecules of methane and diamonds are continuously accumulated on the rough stone of the diamond in the way of microwave high speed. So diamonds grown this way are no different from natural diamonds. You can't tell with the naked eye.

There are two methods of growing gem-grade diamonds in circulation :HPHT and CVD. T(high temperature and high pressure) treatment can be used in the jewelry industry due to its high quality, but it is mostly used in the industrial field. CVD(chemical deposition) treatment has low yield and high technical difficulty, but its quality is generally good, and it has been widely used in gem industry. Diamond in the diamond category, ii type A, is accepted, the ideal and irreplaceable ultra-precision machining tools, is also A good optical window material, ir optical window, as well as A kind of very has the advantage of semiconductor materials. In nature, type II diamond only accounts for 2% of the total, but CVD diamond is all types of diamond, therefore,CVD diamond industry is mainly used in machinery, manufacturing, military, aerospace, science and technology, medical equipment and other high-tech fields, because of excellent diamond thermal conductivity, so in the chip field will have great development in the future, such as CVD diamond can be grafted GN, Improve the heat dissipation capacity of the chip.
