Cuprite and Periclase Optic Character

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

Cuprite and Periclase Transparency

Similar to their colors, Cuprite and Periclase 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, Cuprite is TranslucentWalter Schumann while Cuprite is TranslucentWalter Schumann in appearance.
