• The other polymorphs with identical composition to kyanite are andalusite and sillimanite.
• However, it has mostly been replaced by the other aluminosilicate polymorphs, andalusite and kyanite, for this purpose.
• Rare or unusual gemstones, generally understood to include those gemstones which occur so infrequently in gem quality that they are scarcely known except to connoisseurs, include andalusite, axinite, cassiterite, clinohumite and red beryl.
• The area around Mwami, Zimbabwe is known to contain modalite, topaz, quarts and andalusite. Large crystals of euclase and other minerals have been mined from the area.
• Andalusite is trimorphic with kyanite and sillimanite, being the lower pressure mid temperature polymorph.

• It occurs commonly as an alteration product of corundum, andalusite and other aluminous minerals.
• 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.
• Metamorphic facies range from high-pressure kyanite to low-pressure andalusite.
• Typical associated minerals include: kyanite, andalusite, topaz, mica and quartz.
• Since 1910, the "Prix Gosselet" is awarded every four years for accomplishments made in the field of applied geology. The mineral gosseletite, a phase of manganian andalusite, is named after him.

• Knotenschiefer is a variety of spotted slate characterized by conspicuous subspherical or polyhedral clots that are often individual minerals such as cordierite, biotite, chlorite, andalusite and others.
• The original shales transformed into mica schists of the "cordierite, andalusite and sillimanite zone" in the lower part of the section, higher up they only converted to greenschist facies phyllites of the "biotite zone".
• It is a group of metamorphic minerals - sillimanite, kyanite and andalusite.
• The county has several mineral resources such as rock salt, limestone and andalusite.
• Elbaite forms in igneous and metamorphic rocks and veins in association with lepidolite, microcline, and spodumene in granite pegmatites; with andalusite and biotite in schist; and with molybdenite and cassiterite in massive hydrothermal replacement deposits.
