FAQ

Frequently Asked Questions

Trichroism is the optical property where a crystal exhibits three different colors when viewed along different crystallographic directions, due to anisotropic light absorption.

It is primarily used in mineralogy, gemology, geology, and materials science for describing, identifying, and studying anisotropic crystals and gemstones.

Pleochroism is a broader term for showing multiple colors in anisotropic materials, while trichroism specifically refers to the display of three colors.

No, trichroism is specific to certain crystals and gemstones; it is not observed in everyday objects and requires specialized knowledge to identify.

The property of certain crystals to exhibit three different colors when viewed along different crystallographic axes.

Trichroism is usually technical/scientific in register.

Trichroism: in British English it is pronounced /ˈtraɪkrəʊɪzəm/, and in American English it is pronounced /ˈtraɪkroʊɪzəm/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Remember 'tri-' means three and 'chro-' relates to color, so trichroism is about three colors in crystals.

Conceptual Metaphor

A trichroic crystal is like a prism that reveals different hidden colors depending on how you look at it.
