Moss Agate and Phlogopite optical properties play a significant role while distinguishing these gemstones from each other. These properties are influenced by the Moss Agate and Phlogopite 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 Moss Agate and Phlogopite 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.
Similar to their colors, Moss Agate and Phlogopite transparency can also be used as criteria for their primary identification.
