Axinite and Microcline optical properties play a significant role while distinguishing these gemstones from each other. These properties are influenced by the Axinite and Microcline Physical Properties like crystallographic symmetry, pleochroism,etc. in the crystal. Some of the optical properties are refractive index, luster, optic character, pleochroism etc. Prominent among these is Axinite and Microcline optic character. You might have noticed your gemologist rotating the gemstone while testing it. Rotating a gemstone along its optic axis helps in determining its optic character. Axinite has Biaxial/+ character.
Similar to their colors, Axinite and Microcline transparency can also be used as criteria for their primary identification. Although transparency cannot be the only criteria for gemstone identification, it can efficiently used in gemstone grading. Talking about their transparency, Axinite is while Axinite is in appearance.
