Leucite and Orthoclase Optic Character

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

Leucite and Orthoclase Transparency

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