The chemical composition of beryl is Be3Al2[Si6O 18], and its crystal belongs to hexagonal cyclic silicate mineral. Crystals are usually hexagonal cylinders with longitudinal stripes on the surface. Aggregates are sometimes clustered or needle-shaped, and sometimes they can form giant crystals, which can be up to 5 meters long and weigh 18 tons. Mostly light green, pink when rich in cesium, known as rose beryl; When containing chromium, it is bright emerald, which is called emerald; When it contains ferrous ions, it is light blue and is called aquamarine; When it contains trivalent iron, it is yellow and is called yellow emerald. Glass luster, not perfect cleavage. Mohs hardness is 7.5-8, and specific gravity is 2.6-2.9.
Beryllite is mainly produced in granite pegmatite, greisen and high temperature hydrothermal veins. Beryl is the main mineral raw material for smelting beryllium, and precious stones with beautiful colors, such as emeralds and aquamarine, etc.
