Sinhalite and Periclase Optic Character

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

Sinhalite and Periclase Transparency

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