Natural agate rough stone - mother and child love has recorded that because the agate's original stone shape is similar to that of the horse's brain, it is called "the yellow stalked onyx - the holy man's topping map." Whether in the Old Testament or the classics of Buddhism, there are records of agate's deeds. In the East, it is one of Qibao and Qizhen. Agate can be divided into chalcedony and agate. The original stone color is not complicated, called "chalcedony", and the original stone with straight parallel stripes is called "streaked agate" (sliced ​​agate). According to the color of the original stone, there are also sardine agate, crimson agate and so on. The history of agate is very far away. About 100 million years ago, underground magma spewed out a lot due to changes in the earth's crust. When the lava cooled, steam and other gases formed bubbles. The bubbles are sealed when the rock freezes to form a number of holes. A long time later, the hole was immersed in a solution containing silica to condense the colorful agate rough stone - the woodpecker became a silica gel. The fusible component of the iron-containing rock enters the silica gel, and finally the silica crystallizes into agate. In mineralogy, it belongs to the chalcedony, which is a stone pulp with different colors and a band-like distribution. It is usually a multicolored water grass agate sculpture - the dragon is gradually filled with a colloid of silica along the peripheral wall of the cavity or void of the rock to form a concentric layered or parallel layered block. It is generally translucent to opaque, with a hardness of 6.5 to 7 degrees, a specific gravity of 2.55 to 2.91, and a refractive index of 1.535 to 1.539. Agate can be formed in both igneous and sedimentary rocks in various geological history. Therefore, there are a lot of agates and the difference in color is also great. According to the pattern and color, there are names such as agate, moss agate and jasper agate. Agate is used as a gemstone or a craft product because of its rich color and beautiful appearance. It can also be used to make bearings for precision instruments and agate carcasses, agate white agate rough stone, Yang Guifei and other industrial products. The famous agates in the world are: India, Brazil, the United States, the original stone of the Onyx - Yutu and Australia, Mexico and other countries. Mexico, the United States and Namibia also produce agate with lace-like stripes called "lace agate." Yellowstone, Wyoming, and Montana also produce "scenery agate." China's agate production area is also widely distributed, almost all provinces, famous places are: Yunnan, Heilongjiang, Liaoning, Hebei, Xinjiang, Ningxia, Inner Mongolia and so on.
