Euclase and Rubellite Optic Character

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

Euclase and Rubellite Transparency

Similar to their colors, Euclase and Rubellite 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.
