Covellite and Scolecite Optic Character

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

Covellite and Scolecite Transparency

Similar to their colors, Covellite and Scolecite 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.
