Chrysoberyl Gemstones

Chrysoberyl is a beryllium aluminum oxide mineral with the chemical formula BeAl₂O₄. This gemstone forms under high-temperature and high-pressure conditions typically found in phlegmatic veins or metamorphic rocks. It originates from the cooling and crystallization of magma deep within the Earth's crust, where beryllium and aluminum-rich fluids interact. Chrysoberyl is renowned for its hardness, ranking 8.5 on the Mohs scale, and its unique optical properties, particularly in its varieties such as alexandrite, which can change color under different lighting conditions. The chemical stability of chrysoberyl makes it resistant to weathering and chemical reactions, ensuring its durability and brilliance as a gemstone over geological time.
