Chalcedony and Copper Optic Character

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