Olivine crystallizes in the mantle magma pool and is extremely resistant to high temperature. At the same time, olivine is a rare gem, which was also formed in outer space and found on the moon and Mars. In addition, the high temperature resistance of olivine enables it to resist the high temperature when passing through the atmosphere and safely "reach" the earth, so there is also olivine in meteorites.
Gem-grade olivine is mainly distributed in China, USA, Pakistan and Myanmar. Among them, China Jilin Dunhua Jisongshan olivine gem mine has the largest amount of original olivine that can be mined in the world. Through sampling test, all olivine samples have reached the gem level, with bright colors and few inclusions.
Olivine action
Olivine is not only used in jewelry, but also widely used in industrial production. For example, forsterite and sand for steel parts produced in China have the functions of high temperature resistance, corrosion resistance and good stability. This is because the high melting point of forsterite makes it a good refractory (the melting point of pure forsterite can reach 1890℃).
At the same time, industrial grade olive sand and basalt are widely used. Industrial grade olive sand is a natural and environmentally friendly substitute for other industrial abrasives, which can be widely used in metallurgical accessories, high manganese steel and other materials. On the other hand, basalt is also widely used in architecture, industry and highway engineering. In particular, crushed basalt can be used for subgrade, concrete aggregate, asphalt pavement aggregate, railway ballast, filter stone in drainage field and other purposes, and can also be made into fine, fine and superfine fibers, which have excellent thermal stability, heat resistance, sound insulation, seismic performance and durability.
