Phosphophyllite and Euclase Optic Character

Phosphophyllite and Euclase optical properties play a significant role while distinguishing these gemstones from each other. These properties are influenced by the Phosphophyllite and Euclase 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 Phosphophyllite and Euclase 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.
