Covellite and Rose Quartz Optic Character

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

Similar to their colors, Covellite and Rose Quartz 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.
