Do you know Artificial diamonds ?
Artificial diamonds, also known as synthetic diamonds, are grown in laboratories. It is a diamond that is generated and manufactured by simulating the characteristics of natural diamond generation under artificial conditions. It is basically the same with natural diamond in terms of chemical composition, crystal structure and physical properties. Nowadays many countries in the world attach great importance to the technology of synthetic diamond and begin to make extensive use of synthetic diamond.
In the past, due to the narrowness of people's perception, many people believed that the artificially produced gems were fake and worthless. In fact, this idea was wrong. As early as 1916, Japanese gemologists proposed the classification of gemstones. Over the years, gemologists at home and abroad have made a variety of classification schemes based on the application field of gemstones, commodity value, gem grade, mineral and rock characteristics, etc., but they are not uniform and impartial. In order to better regulate the jewelry market, China began to implement the national standard for jewelry and jade jewelry industry in 1995 (GB/ t-16552-1996). The definition and classification of jewelry and jade are given.
(1) synthetic gems
Synthetic gemstones are artificially produced gems with the same physical properties, chemical composition and atomic structure as natural gemstones, such as synthetic diamonds, synthetic rubies and synthetic emeralds.
(2) collage gems
A gemstone is a gemstone that is assembled by two or more kinds of materials through artificial methods. Although they give an overall impression on the appearance, the appearance of the gemstones will become more and more obvious with the long wearing time, which will affect the overall beauty.
(3) remanufactured gems
Reconstruction, literally, is the regeneration of fragments and residues of some gemstones after artificial fusion, which has lost the natural beauty of gemstones. The common reconstituted gemstone to the reconstruction of amber, the reconstruction of turquoise in the majority. Under the precondition of market regulation, synthetic diamond is to protect the environment, return to the friendly concept of natural and plain, and provide consumers with more and better choices. As a strategic resource, synthetic diamond has important application in many fields such as industry, science and technology and national defense. Both in technology and practicality. The development of synthetic diamond reflects the progress of human society science and technology and the concept of harmonious coexistence of human and nature.
