Chiastolite, also known as Andalusite or Cross Stone, is a variety of the mineral Andalusite (Al2SiO5) that contains carbonaceous inclusions. It belongs to the orthorhombic crystal system and typically forms prismatic crystals with a distinctive cross-shaped pattern when viewed in cross-section. Chiastoltie's enchanting cross is caused by inclusions that often appear as dark, parallel rods or fibers that intersect at right angles, giving Chiastolite its characteristic appearance. The cross-shaped pattern of chiastolite is formed by carbonaceous material, often graphite or coal, that replaces parts of the andalusite crystal lattice during metamorphism.

The name "Chiastolite" is derived from the Greek word "Chiastos" meaning "Cross". It refers to the characteristic cross-shaped pattern that is visible in its crystals when viewed in cross-section. Chiastolite is primarily formed during regional metamorphism of clay-rich sediments or pelitic rocks that contain aluminum and silica.

Chiastolite has been prized for its unique appearance and has been used historically in amulets and talismans for protection and spiritual grounding. The cross pattern is often interpreted as a symbol of protection, balance and harmony. Ancient Egyptians believed that stones with cross patterns held protective properties and were often used in burial rituals. The stone was thought to safeguard the soul in the afterlife. In cultures all across the globe, the cross symbol was often associated with the connection between the physical and spiritual worlds, making it a revered stone among shamans and healers.

Chiastolite is an enchanting gem of good luck, health and protection. Its protective energy helps shield the aura from negative energy and safeguard the physical body. Chiastolite is a powerful stone for attracting good luck, abundance and prosperity. It can be used to direct energy because of its cross pattern and open circles or portals. Chiastolite has a deep connection to the Earth through the Root chakra for grounding and healing. It holds ancient wisdom and makes a great crystal for channeling, shamanic journey, and past life recall.
