Kyanite in plane-polarized and cross-polarized light, showing high relief, good cleavage and parting, and first-order (saturated) interference colors. Muscovite around it shows undulose (sweeping) extinction. Note that this section is a little thick, so many quartz grains are yellow in cross-polarized light.
