description Axinite Overview
Axinite is a group of calcium-bearing borosilicate minerals known for strongly pleochroic colors, in which the apparent color changes with viewing direction. Its crystals commonly have flattened, wedge-like forms, and specimens may range from brown and violet to yellow or gray. Axinite occurs mainly in metamorphic and metasomatic rocks and is collected both as a mineral specimen and, when transparent enough, as a gemstone.
help Axinite FAQ
What is axinite?
Axinite is a group of calcium-bearing borosilicate minerals. Its crystals commonly have flattened, wedge-like forms and may be brown, violet, yellow, or gray.
Why does axinite appear to change color?
Axinite is strongly pleochroic, meaning its apparent color changes when viewed from different directions. This optical effect is especially noticeable in well-formed crystals.
What colors can axinite crystals have?
Axinite specimens may range from brown and violet to yellow or gray. The exact appearance depends on the mineral composition and viewing direction.
What shape do axinite crystals commonly have?
Axinite crystals commonly have flattened, wedge-like forms. That crystal habit, together with strong pleochroism, helps distinguish the group.
