Zircon (natural zircon, not synthetic cubic zirconia): Low-type zircon has serious radiation and will cause harm to human body. But because of the beautiful color of low-grade zirconium, there are also some merchants. However, in China, there are few natural zircon for sale, because China does not produce precious zircon.
Because natural zircon has radiation and is harmful to human health, it must be treated before it can be worn, so the zircon sold in the market is basically artificial, also called synthetic cubic zirconia, which is also graded. Zircon made by regular manufacturers can even match the appearance of diamonds, which is difficult for non-professionals to identify. Zircon takes a long time to see the difference from diamond. Because its price is much lower than that of diamonds, it can meet people's needs from an aesthetic point of view, and it can buy imitation jewelry with less money, so it also attracts a large number of consumers.
