Zincite and Andesine Optic Character

Zincite and Andesine optical properties play a significant role while distinguishing these gemstones from each other. These properties are influenced by the Zincite and Andesine 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 Zincite and Andesine 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. Andesine has Biaxial/+ character.

Zincite and Andesine Transparency

Similar to their colors, Zincite and Andesine 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, Zincite is The Journal of Gemmology (1995) More from other references and TransparentRobert C.
