Agate

Basic Introduction to Brazilian AgateBrazil is one of the most important sources of Brazilian agate in the world, with particularly famous mines located in the states of Rio de Janeiro, Santa Catarina, Paraná, and Mato Grosso do Sul. Among these, the Minas Gerais region is the largest producer of gem-quality agate. In mineralogy, Brazilian agate belongs to the chalcedony family, a fibrous material that stands out among other gems for its rich colors, warmth, fineness, and high luster. It is highly regarded due to its resemblance to horse brains, which is why it is called "agate."Brazilian agate typically forms in cavities left after volcanic activity, where spaces left by cooled magma are filled with silica-rich hot water. Over long periods of geological time, this gradually crystallizes into agate. Agate is primarily composed of silicon dioxide (SiO₂) and is a variety of quartz. It has a vitreous luster, is translucent to slightly transparent, and has a hardness of about 7 to 7.5 on the Mohs scale, making it sufficiently hard for use in jewelry. Nutritional ValueJewelry Making: Brazilian agate is widely used in the creation of various types of jewelry, such as necklaces, bracelets, and rings, favored for its beauty and…

The primary sources are in the Danjiangkou reservoir area of Hubei and Henan provinces (including the towns of Tan Shan and Liu Dong in Yunxian County, Hubei, and De Sheng in Zhushan, as well as Miao Gang in Neixiang and Wei Ying in Xichuan, Henan).
