The 15 pages that link to Pleochroism, each with the reason it gives.

• GemstoneRelated: Cut orientation can emphasize or reduce a gem’s direction-dependent colors.

• AmphiboleRelated: Iron-bearing amphiboles can show strong directional color changes in thin section.

• SapphireRelated: Sapphire can show different color intensities or hues depending on viewing direction.

• AndalusiteRelated: Andalusite can display different colors along different optical directions.

• DichroismBroader topic: It is a visible crystal-color effect often caused by direction-dependent absorption.

• DiopsideRelated: Iron-bearing diopside can show orientation-dependent color in thin sections and gemstones.

• HornblendeRelated: Hornblende often shows strong pleochroism in thin section.

• TourmalineRelated: Tourmaline’s strong directional color variation follows from its anisotropic crystal structure.

• AugiteRelated: Augite may show weak pleochroism, a useful clue in thin-section examination.

• BiotiteRelated: Biotite commonly shows strong pleochroism in thin sections under a petrographic microscope.

• EpidoteRelated: Many epidote crystals show direction-dependent green or yellow-green colors under polarized light.

• ChrysoberylRelated: Chrysoberyl can show direction-dependent colors, especially noticeable in transparent faceted stones.

• PainiteRelated: Painite can show direction-dependent color, a feature considered when orienting and cutting crystals.

• TanzaniteRelated: Tanzanite can show blue, violet, and reddish-brown hues from different viewing directions.

• TitaniteRelated: Some titanite crystals show direction-dependent colors that affect gem cutting.
