Smoke crystal (also known as smoke crystal, tea crystal or tea crystal) is a type of crystal variety with colors of smoke gray, smoke yellow, yellow brown, and brown. It is best to have a uniform color, no cotton, and clear. Smoke crystal originates in Scotland and is mainly produced in Brazil, the United States, Africa, and other regions.
The main mineralogical properties of smoky crystals are as follows:
Chemical composition: SiO2
Structure: Crystalline body
Hardness: 7
Color: Smoke yellow, brown to black
Mineral composition: Quartz smoke crystal is a solid sol, belonging to colloids.
Main production areas: Brazil, South America, Africa, etc.
Note: In China, smoky yellow and brown crystals are also known as tea crystals; Black crystal is called ink crystal. The color of smoky crystals was previously believed to be caused by impurities, but according to research, its color is due to the presence of extremely trace amounts of radioactive elements (radium).
origin
The pure natural crystal ring is elegant and fashionable. Smoke crystal is one of the most attractive members of the crystal family, abbreviated as Smoke Crystal. Some people believe that the beautiful color of this gemstone is caused by the presence of radium radiation in the surrounding rocks of the primary mineral deposit, but in fact, it is found in the surrounding rocks of the Swiss Alps. The radioactive content varies with altitude. This change causes different differences in the color or hue of the smoky crystals in the region. According to this inconsistent view, experts can have a high degree of confidence in finding the desired crystal and its variants.
The tea crystal in the smoke crystal has a color like smoke floating in the air. Its color is caused by radioactive substances. According to Herba’s research in 1979, when quartz contains aluminum instead of silicon, colorless crystals can be transformed into brown crystals by irradiating them with cobalt-60. The tea colored glasses and accessories on the market are almost all products that change color through radiation. Long ago, some places produced tobacco crystals but did not utilize them.
distribution
The composition of crystal stone is silicon dioxide, which is a hexagonal crystal with crystal tips at the top. It is mostly clustered or has single crystals. Well developed crystal stones are superior stones hunted by stone enthusiasts. There are many varieties of crystals, including white crystal, brown crystal, pink crystal (hibiscus stone), smoke crystal, hair crystal, rainbow crystal, Venus crystal, amethyst, water gall crystal, piezoelectric crystal, etc. Among them, pure amethyst, aquamarine crystal, and piezoelectric crystal are the most valuable; The above two can be used for stone play, while the latter is a non-metallic mineral used in the aerospace industry. China is a major producer of crystals, with the highest output and best quality. The first provinces to produce crystals are Jiangsu and Yunnan. The Xizang Autonomous Region is also rich in crystals, especially amethyst. Its colors include grape purple, purple blue, and light purple, appearing semi transparent to transparent, with large crystal clusters; Colorless crystals are also widely stored in Xizang.
