Taaffeite and Omphacite Optic Character

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

Taaffeite and Omphacite Transparency

Similar to their colors, Taaffeite and Omphacite 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, Taaffeite is Gemmological Tables (2004) More from other references while Taaffeite is Gemmological Tables (2004) More from other references in appearance.
