Omphacite and Beryl Optic Character

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

Omphacite and Beryl Transparency

Similar to their colors, Omphacite and Beryl 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, Omphacite is TranslucentAnthony et al and Handbook of mineralogy (2001) while Omphacite is TranslucentAnthony et al and Handbook of mineralogy (2001) in appearance.
