Copper and Corundum Optic Character

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

Copper and Corundum Transparency
