Dioptase and Orthoclase Optic Character

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

Dioptase and Orthoclase Transparency

Similar to their colors, Dioptase 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.
