Vesuvianite: Background and Summary
Vesuvianite is a mineral that is also known as idocrase. It is a silicate mineral that is typically green, yellow, brown, or blue. Vesuvianite is commonly found in metamorphic rocks such as skarns, marble, and quartzite. It is often associated with other minerals such as garnet, diopside, and wollastonite.One way to identify vesuvianite is by its crystal structure. It typically forms in prismatic or tabular crystals that have a square or rectangular cross-section. The crystals may be elongated along one axis, giving them a needle-like appearance. Vesuvianite also has a distinctive cleavage pattern, which is a property that allows it to break along certain planes. It has a vitreous to resinous luster and a hardness of 6.5 on the Mohs scale.
Vesuvianite has several uses in industry and jewelry making. It is commonly used as a gemstone due to its attractive colors and high clarity. The green variety of vesuvianite is often referred to as California jade or California emerald. It is also used as a decorative stone in carvings and sculptures. In industry, vesuvianite is used as a refractory material in high-temperature applications such as furnace linings. It is also used as a flux in the production of steel and as a source of calcium in the production of cement.
