Andesine and Pyrope Optic Character

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

Andesine and Pyrope Transparency

Similar to their colors, Andesine and Pyrope 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, Andesine is Translucent, Transparent and Transparent to translucent while Andesine is Translucent, Transparent and Transparent to translucent in appearance.
