Orthoclase and Linarite Optic Character

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

Orthoclase and Linarite Transparency

Similar to their colors, Orthoclase and Linarite 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, Orthoclase is Gemmological Tables (2004) More from other references while Orthoclase is Gemmological Tables (2004) More from other references in appearance.
