Carnelian and Schultenite Optic Character

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

Carnelian and Schultenite Transparency
