buy wholesale sterling silver jewelry How is artificial diamond made?

22k indian real gold jewelry wholesale Have you heard of "Diamond Scam"? Diamonds are long -lasting, a forever spread. The essence of the diamond is carbon mono. Although the crystal clear and glittering eye, it can make artificially use graphite in a high -temperature and high -pressure environment. The "scam" statement comes.
The diamonds are generated by some extreme changes in the history of the earth. For example, the high temperature and high pressure environment under the hits of the asteroid hit the earth, and there are many such events in the history of the earth, as well as underground pressure and temperature of the underground itself, temperature, temperature It is higher and may also form diamonds, but due to the buried location, it is difficult to minimize, and the limit of diamond volume and hardness, the difficulty of processing in the later period is also higher, so the diamond is expensive and the material is rare. In a very extreme environment, a huge diamond can be generated. The largest diamonds that are naturally found by human beings currently discovered are the African star diamonds weighing 3106 carats.
and now human technology can simulate the environment of diamond generation, use carbon to make diamonds. In the high temperature and high pressure environment of 2300 ° C and 150,000 to 180,000 atmospheric pressure, put a small natural diamond in the center as Seeds are high -temperature metal liquid around the seed diamond, and the upper layer of the metal solution is graphite. In this environment, the carbon atom in graphite will queue up from the metal atom to the diamond to form a new diamond. However, the diamond molecular structure made in this method is not a complete octopus structure of natural diamonds, but a complex structure, and the volume is also limited.
So to a certain extent, artificial diamonds really cannot compare with natural diamonds. However, because the appearance seems not much different from natural diamonds, it is mainly due to post -processing, and falsification is relatively low, and it is also very popular. Isn't it finished? However, this is not the case. People are a little vanity. Wearing a natural diamonds formed millions of years ago and the short -term artificial diamonds in the laboratory, of course, the former is easier to satisfy people's psychology.

wholesale beads and jewelry supplies canada Artificial diamonds are mainly divided into three methods: 1. High temperature pressure method; 2. Zhen wave method; 3. Chemical phase precipitation method
