The more extreme beauty in the world, the more dangerous it is. The goblin on the TV is also very beautiful; bright mushrooms after the rain can put down a few big men; with surprisingly beautiful snakes or frogs, the toxicity is the biggest! Under the beautiful gemstone appearance, there is also a secret hidden in the unknown!
Radioactive gemstone
Do you still remember that the male leader of the "Hawthorn Tree Love" directed by Zhang Yimou is a geological worker. Because he sent a "specimen" into the provincial capital, he was diagnosed with leukemia, which is subject to the "specimen". "The radiation caused! I am not sensational. Of course, you don't have to be afraid. Unless you are specialized in mining and other related work, it is generally impossible to receive such strong mineral radiation!
But if there is uranium in the natural gemstones, you should pay attention!
Uranium is an important natural radioactive element. After the discovery of uranium nuclear fission in 1938, it began to become a major nuclear material and was also used as a detonator for thermal nuclear weapons hydrogen bombs. Although it is only weakly radioactive, you should know how to accumulate less.
Zircon
When it comes to zircon, many people are expected to wear diamond-like gemstones, which used to be called zircon or hyacinth. But don't worry, most natural zircon components contain radioactive elements such as uranium (U) and thorium (Th). But the content is very low, far below the safety factor. Everyone can wear it with confidence. Of course, some fake and shoddy zircons are excluded! In gemology, it is classified into three types: "high type", "medium type" and "low type" based on the degree of refractive index, hardness and density of radioactive elements in zircon.
Among them, high-type zircon is the least affected by radioactivity and is used as a common gem. However, the color of the low-type zircon, which is usually green, grayish yellow, brown and orange, should be taken care of. Such zircon still has a certain amount of radioactivity, which may not be affected in the short term. It is difficult to say in the long run. In general, artificial heat treatment of zircon will reduce or even eliminate the radioactivity of zircon. So, for natural zircon, you can rest assured.
fluorite
Another gemstone with certain uranium is fluorite, also known as fluorite. Fluorite is named because it fluoresces under ultraviolet or cathode radiation, but when fluorite contains some rare earth elements, it emits phosphorescence. When heated, its color can be removed, it can be recovered by X-ray irradiation, and the color causes are diverse. It is worth noting that some purple-black fluorites contain high levels of radioactive elements. Some of the ancient night pearls may be fluorite. Fluorite generally requires care to avoid violent collisions while avoiding exposure to chemicals. Due to its brittleness and low hardness, it is not recommended as jewelry. Most of the night pearls on the market are made of rare earth elements. The appearance is light blue-green and has a certain radioactivity, so try to avoid buying.
There is no perfect thing in the world, many gems are artificially optimized and then reborn, the effect is no less than today's plastic surgery!
Irradiation color change
Gemstones that have been artificially irradiated. The most common is the irradiated topaz.
Generally, regular manufacturers will be allowed to stand for a period of time after irradiation, and then they will be sold on the market. The radiation of such gemstones has no harm to the human body.
Jade B goods C goods
B goods C goods jade is not a natural jade, but the jade that has been pickled, waxed and glued. B, C goods jade production is simply terrible, so many chemicals, for the technicians are more or less toxic.
In the long-term wearing process, the human body and its constant friction, those chemicals will also slowly infiltrate into the human body, so it is harmful to the human body to wear B, C goods jade, so I still hope that you still have to buy the jade of A goods!
Be sure to choose a quality-assured merchant to make a purchase, and don't let any black-hearted business have a profitable opportunity.
