A variety of the mineral andalusite with the chemical composition Al2SiO5. It is noted for distinctive cross-shaped black inclusions of graphite. In areas around Georgetown, California, metamorphosed sediments contained andalusite and the stone in a graphite rich metasediment.
Crystals have been pseudomorphically altered by a mixture of muscovite, paragonite and margarite. The calcium rich margarite tends to form along the graphite rich crosses or bands within the stone. Mineralogically the occurrence is important because all three white mica phases are present in an equilibrium assemblage.
There are several theories regarding the formation of the chiastolite cross, however the most widely accepted theory, proposed by Frondel in 1934, suggests that there is a selective attachment of impurities at the rapidly growing corners of andalusite crystals.
As the concentration of these impurities (which consist primarily of graphite) increases, the growth of the crystal is slowed. This concentrated impurity deposit forms a re-entrant as it is absorbed by the growth of the andalusite porphyroblast. The cycle of growth-retardation-growth then repeats itself, creating a featherlike pattern of graphite along four radiating ‘arms’.
Chiastolite from Mogok, Myanmar (Burma)
Andalusite is an aluminium nesosilicate mineral with the chemical formula Al2SiO5. This mineral was called andalousite by Delamétehrie, who thought it came from Andalusia. It soon became clear that it was a locality error, and that the specimens studied were actually from El Cardoso de la Sierra, in the province of Guadalajara, not Andalusia.
Andalusite is trimorphic with kyanite and sillimanite, being the lower pressure mid temperature polymorph. At higher temperatures and pressures, andalusite may convert to sillimanite. Thus, as with its other polymorphs, andalusite is an aluminosilicate index mineral, providing clues to depth and pressures involved in producing the host rock.
Chiastolite meaning and healing properties
The following section is pseudo scientific and based on cultural beliefs.
The crystal has powerful metaphysical properties. For meditation, this will help you attach with the Akashic records so that you will be able to find out previous life information. The crystal will also transform negative energies into positive ones and foster peace and harmony.

What chakra is chiastolite?
The crystal helps one open up their root chakra and connect their energies to that of mother Earth.
Where is chiastolite found?
The stone was first found in Andalusia, a Province of Spain which gave its name to the parent mineral. Other world localities of note are South Australia, Brittany, France, and the trans Baikal province of the USSR at Nerchinsk and on the shores of the Argun river.
