Nano Polycrystalline Diamond and Pyrite Optic Character
Nano Polycrystalline Diamond and Pyrite optical properties play a significant role while distinguishing these gemstones from each other. These properties are influenced by the Nano Polycrystalline Diamond Vs Pyrite 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 Nano Polycrystalline Diamond and Pyrite 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.
