Charoite and Sarcopside Optic Character
Charoite and Sarcopside optical properties play a significant role while distinguishing these gemstones from each other. These properties are influenced by the Charoite and Sarcopside 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 Charoite and Sarcopside 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.
Charoite and Sarcopside Transparency
Similar to their colors, Charoite and Sarcopside 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, Charoite is Translucent while Charoite is Translucent in appearance.
