Beryllite is produced in nature, and its main component is Be3Al2[Si6O 18], which is a hexagonal beryllium aluminum silicate mineral. Emerald is formed because it contains a proper amount of Cr2O3(0. 15~0.6%). It is the most outstanding member of beryl family. This material belongs to high-grade gem.

Its color source is: a small amount of chromium oxide makes it appear crystal clear and beautiful green.

Physicochemical composition Emerald is a silicate containing beryllium and aluminum, and its molecular formula is Be3Al2[Si6O 18], which belongs to the noblest member of beryl family. It belongs to hexagonal system. Crystal simplex is hexagonal column and hexagonal bipyramid, mostly rectangular column. Aggregates are granular, blocky, etc. Emerald green, glass luster, transparent to translucent. The refractive index is 1.564- 1.602, the birefringence is 0.005-0.009, and the polychromatic property is not obvious. Not an isotropic body. The hardness is 7.5 and the density is 2.63-2.90g/cm3. The cleavage is incomplete, and the shell breaks. Fragile. Under the irradiation of X-rays, emeralds emit very weak pure red fluorescence.
