Chiastolite is a variety of andalusite. Let’s first look at what is andalusite?

The chemical formula of andalusite is Al2 [SiO4] O. AI in the composition can be partially replaced by Fe and Mn, and Ti can slightly replace Si.

When the content of Mn2O3 is high (about 7%~10%), it is called manganese andalusite and is a variety.

Andalusite belongs to orthorhombic system and is an orthorhombic column extending along the C-axis. The angle between the cylinder and the square column is 89 ° 12 ‘, which looks similar to the square column, and the cross-section is nearly square;

The aggregate may be in radial shape. Black carbonaceous inclusions are often contained in the crystals, which are distributed in a strip along the extension direction.

According to observation on the crystal cross-section, the inclusions are distributed in a cross shape along the diagonal direction.

This andalusite is called Chiastolite, which is another variety of andalusite.

Basic properties, origin and occurrence of andalusite

1) Mohs hardness: 6.5 ~ 7.5.

2) Cleavage: {110} Cylindrical cleavage is complete.

3) Density: 3.1~3.2g/cm.

4) Optical property: inhomogeneous body, biaxial crystal, negative optical property.

5) Refractive index: 1.629~1.647, birefringence: 0.007~0.011.

6) Gloss: glass luster.

7) Color: flesh red, green, blue, yellow, brown, purple, colorless, etc.

8) Polychromism: Colored people are moderate to strongly polychromatic.

9) Transparency: Transparent to translucent.

10) Origin and occurrence: andalusite is a typical low-grade thermal metamorphic mineral which is commonly found in hornfels, crystalline schists and gneisses.

What is Chiastolite?


Chiastolite is generally white or gray, light red or light brown. In the center of the cross-section of the crystal, dark cross-shaped bands are visible, which are formed by the aggregation of wrapped carbon.

This carbon band can extend from one end of the crystal to the other along the longitudinal axis, but the thickness and shape of the band will vary.

The hardness of Chiastolite is reduced to 5 ~ 5.5, and the relative density is 3.10 ~ 3.20 due to the inclusion. Massachusetts in the United States, Siberia in Russia and South Australia are famous sources of Chiastolite.

It is often cut and ground into amulets and exorcists and is known as “black cross-stone”.

In Xixia, Henan Province, China, there are good megacrysts of Chiastolite. The diameter of the cross-section is generally 10~30mm, some can reach 60mm, and the column length can reach 20cm.

Basic Properties of Chiastolite

Color: black, brown, reddish brown

Hardness: 6.5~7.5

Cleavage: incomplete cleavage

Crystallization system: orthorhombic system

Main origin: America, Russia, South Africa, France

Energy form of Chiastolite

Chiastolite belongs to the orthorhombic system, which can clean up negative energy and bring profound energy to help people find their inner beliefs and determination to practice truth.

It has an excellent effect on the situation that people often complain about. Chiastolite contains carbon, which can anchor the meaning of personal life, re-establish the determination to live seriously and find a way to settle down in the environment.

The Healing meaning of Chiastolite

Chiastolite is a powerfully protective stone with the ability to turn hostility into friendship, which helps solve the problem.

As early as in ancient times, people used it to dispel evil thoughts and warm spells to resolve disputes.

Therefore, this kind of stone has always been associated with the word “mysterious”.

It is said that it can also promote the “soul to wear out”, facilitate the performance of mysterious events such as reincarnation, and encourage the understanding and exploration of eternal life. Similar statements have attracted the attention of many crystal fans.

However, in the eyes of modern people, Chiastolite exists more as a stone of creation. It is said that it can break the old thought pattern psychologically and effectively eliminate people’s illusions and negative feelings (such as guilt and anxiety) so that people can face reality and get rid of fear. When encountering sudden environmental changes, this kind of stone is said to help people adapt to circumstances and solve problems through comprehensive analysis.

According to crystal fans, it can also play a good role in protecting people from illness or injury and maintaining their spirituality.

Chiastolite can reduce fever and stop bleeding: relieve excessive gastric acid, treat rheumatism and gout: treat paralysis, helpful for lactation, Repair damaged chromosomes: coordinate the immune system: and strengthen the stability of the nervous system.

How to Use Chiastolite

People can wear Chiastolite jewellery to help them establish a stable life, find their beliefs in life, and try to live according to their own ideas.

Chiastolite is also very helpful for the lack of life goals, the lack of confidence in the future, and the fact that the mind cannot always be stable.

When is it good to use Chiastolite?

  • When stability is required
  • When feeling helpless and powerless.
  • When looking for the direction of life
  • When you are not satisfied with your current life

How to clean the Chiastolite?

Purification mode

Except for the water flow method, other purification methods can


Chiastolite is a variety of andalusite, which is a different form of the same mineral as kyanite crystal. It absorbs clay and carbon elements in the formation stage and forms a black part.

These black parts are arranged directionally in the crystal and will naturally form a cross-shaped structure after cross-cutting. They are very popular with Catholics.

In medieval Europe, they are considered to be the embodiment of Jesus Christ, and where they appear are called miracles.
