Chiastolite is a variety of “Andalusite,” which contains cross shaped inclusion of carbon. It was named “chiastolite” due to the distinctive cross-shaped pattern that is often seen when the stone is cut perpendicular to its long axis.
The name “Andalusite” is derived from the region of Andalusia in Spain, where it was first discovered.
Chiastolite can be seen in various locations around the world, including Spain, Russia, Brazil, Sri Lanka, Australia, and the United States. It occurs in metamorphic rocks formed under high temperature and pressure conditions.
It is a polymorphic variety of the mineral andalusite and belongs to the orthorhombic crystal system. It typically occurs in prismatic or columnar crystals with a distinct cross-shaped or chiastolite pattern.
The cross is formed by dark carbonaceous inclusions that are arranged in a cross section within the crystal. Chiastolite has a hardness of 6.5 to 7.5 on the Mohs scale and displays a vitreous to resinous luster. Its color ranges from brown to reddish-brown, and its transparency is often opaque.
Chiastolite has various uses and applications. It is basically used as a decorative or ornamental stone in jewelry and carvings due to its unique cross pattern.
It is believed to have metaphysical properties, such as grounding and protection. It is also associated with balancing energies and enhancing insight and intuition.
The value of chiastolite varies based on factors such as size, color, clarity, and the presence and quality of the cross pattern.
