It is especially helpful if we are grieving or on “death watch” for a loved one. It helps us to understand and accept the harsh reality of death and the dying process, while also bringing us peace and hope that rebirth and immortality are possible for us and our loved ones. It helps us to stay patient and present, regardless of whether the dying process is quick or slow. If we feel that we are not handling things “the right way,” Chiastolite gently gives us permission to forgive ourselves for whatever sin we think we’ve committed and to do our best to meet our own emotional expectations. Chiasolite strongly encourages us to not allow our emotions to run too wild, but instead to seek out a rational and compassionate perspective.

Chiastolite reminds us that we don’t get to control other people’s thoughts or actions. We are only responsible for ourselves, so we need to act in a way that supports our Highest Good.

Where does Chiastolite come from?

Chiastolite crystal deposits have been found in Australia, Belgium, Brazil, Chile, Germany, Russia, Spain, Sri Lanka, and the United States.

Mining and Treatments

Chiastolite is mined at its primary location, usually as a result of Corundum (Ruby and Sapphire) mining.

All Andalusites are fully natural, enhanced only by tumbling, cutting, and polishing. Chiastolites are always cut along a cross section in order to show their distinctive cross.

Mineral Family

Chiastolite is a yellowish-brown variety of Andalusite, famous for its distinctive black cross. Andalusite is a nesosilicate mineral.  Silicates are minerals which contain the elements silicon (a light gray shiny metal) and oxygen (a colorless gas). Together, these two elements form a tetrahedron – a shape similar to a pyramid – with a silicon atom in the center and oxygen atoms at each of the four corners. These tetrahedra connect with other chemical structures, in six different ways, to form various minerals and rocks. There are six main groups of Silicate minerals. Chiastolite belongs to the nesosilicates group, in which the Silicate tetrahedra are not directly attached to each other.

Chiastolite’s energy works well with its family – other nesosilicate minerals.  Try it in combination with Dumortierite, Garnet (Almandine, Grossular, Hessonite, Rhodolite, Uvarovite), Kyanite. Peridot, and Topaz

Chiastolite Formation and Crystal Associates

Chiastolite is commonly found in metamorphic rocks, where it is often in association with Corundum (Ruby and Sapphire), and Kyanite. On occasion, Chiastolite may form in igneous rocks, particularly Granite. The actual formation process is still a mystery and several different theories have been postulated. The most widely-accepted theory is that when pure yellow-brown Andalusite is forming, impurities, principally made up of Graphite, begin to attach themselves to the corners of the Andalusite crystals. As the concentration of impurities grows, it temporarily slows down the growth of the crystal. Eventually a pattern of four radiating lines of Graphite emerges across the Andalusite.

Chiastolite’s energy works well with its “friends” – crystal associates formed in the same geological environment.  Try it in combination with Almandine Garnet

History of Chiastolite

Chiastolite’s distinctive cross has long made it a favorite in lapidaries, texts that describe gemstones and their powers. Its name has two potential origins. It may come from the Greek word chiastos, meaning “cross,” or from the Greek work Chi which is the name for the Greek letter “X.” It is also called Lapis Crucifer or “cross-stone” in many of the oldest lapidaries.

Chiastolite’s metaphysical properties have been particularly celebrated since the rise of Christianity, and its natural cross has long been seen as having mystical and religious significance. In Europe, one of the largest deposits of Chiastolite can be found near the Shrine of St. James in Santiago de Compostella, Spain. According to legend, these Chiastolites are actually holy relics which have been petrified and should be carried during religious pilgrimages. In medieval times, Chiastolite was used to keep the “evil eye” at bay. Today, it is often carried as a sign of devotion, bringing a sense of peace in death and the promise of re-birth.
