Demantoid and Chalcopyrite Optic Character

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

Demantoid and Chalcopyrite Transparency

Similar to their colors, Demantoid and Chalcopyrite 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, Demantoid is Gemmological Tables (2004) while Demantoid is Gemmological Tables (2004) in appearance.
