Baryte, barite or barytes (/ ˈ b ær aɪ t, ˈ b ɛər-/ BARR-eyet, BAIR-[7] or / b ə ˈ r aɪ t iː z / bə-RYTE-eez [8]) is a mineral consisting of barium sulfate (BaS O 4). [3] Baryte is generally white or colorless, and is the main source of the element barium.
The crystals exist in the high-temperature α phase and low-temperature β phase, abbreviated as BBO; both phases are birefringent, and BBO is a common nonlinear optical material. Barium borate was discovered and developed by Chen Chuangtian and others of the Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences .

The dissolved elements start to precipitate out of the solution and form crystals as the hydrothermal fluids cool and come into contact with the right minerals and circumstances. Crystals of beryl, which include aquamarine, begin to form in pegmatite veins and host rock fissures or cavities.
Scientists successfully filmed sound waves in a diamond crystal structure for the first time ever using an X-ray free-electron laser (XFEL).
The high water content of the magma made it possible for the crystals to grow quickly, so pegmatite crystals are often quite large, which increases the likelihood of gem specimens forming. Chrysoberyl can also grow in the country rocks near to pegmatites, when Be- and Al-rich fluids from the pegmatite react with surrounding minerals.
