Cerussite and Anthophyllite optical properties play a significant role while distinguishing these gemstones from each other. These properties are influenced by the Cerussite and Anthophyllite 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 Cerussite and Anthophyllite 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. Anthophyllite has Biaxial/+ character.
Similar to their colors, Cerussite and Anthophyllite 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, Cerussite is Translucent and Transparent while Cerussite is Translucent and Transparent in appearance.
