Periclase and Orthoclase Optic Character

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

Periclase and Orthoclase Transparency

Similar to their colors, Periclase and Orthoclase 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, Periclase is Gemstones of the world (2001) More from other references and TransparentWalter Schumann while Periclase is Gemstones of the world (2001) More from other references and TransparentWalter Schumann in appearance.
