Omphacite and Titanite Optic Character

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

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