Artificial Lab Created Diamonds Description

 

CVD stands for chemical vapor precipitation, another method for making diamonds in the laboratory. The growth of such diamonds requires the application of the appropriate pressure and temperature to the hydrocarbon mixture in a vacuum chamber.

Artificial diamond is a kind of diamond crystal polymer from 10 to 30 nanometres in diameter, the early artificial diamond due to the nitrogen atoms in the air into the diamond crystal and light sugar thin color, after scientists improve the production method, the production of artificial diamond in appearance and natural diamonds have no difference.

Because of 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 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.

Chemical Vapor Deposition synthesis PECVD (Plasma Enhanced Chemical Vapor Deposition): heating natural gas and hydrogen, a kind of carbon plasma is formed in the pressure chamber the size of dishwasher. The plasma is continuously deposited on the carbon bottom layer at the bottom of the pressure chamber and gradually accumulates and hardens to form diamond flakes, which are then cut into gem shapes. Size of 8.2 mm yellow diamond with high quality, the sample for weight and size of the largest mainland synthetic diamond single crystal. This results in the domestic synthetic diamond (diamond gem grade) field has a leading position.

Artificial Lab Created Diamonds Introduction

 

Cut CVD synthetic diamonds look exactly like natural diamonds and are difficult to easily distinguish.The production of lab-grown diamonds has advanced rapidly. Today, lab-grown diamonds cost significantly less than natural diamonds. And synthetic diamonds of all sizes can be grown in the lab.

The diamond produced by CVD synthesis method and HPHT synthesis method has different gemological characteristics. The diamond produced by CVD synthesis method usually has higher transparency and almost no small dark inclusions.

The identification of synthetic diamonds requires specialized identification institutions and identification instruments. Due to the high cost of design technology and equipment, only a few laboratories in the world have the ability to identify synthetic diamonds and natural diamonds. The international identification institutions of synthetic diamonds are IGI International Gemological Institute and GIA American Gemological Institute.
