Crystal Quartz and Fayalite Optic Character
Crystal Quartz and Fayalite optical properties play a significant role while distinguishing these gemstones from each other. These properties are influenced by the Crystal Quartz and Fayalite 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 Crystal Quartz and Fayalite 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.
Crystal Quartz and Fayalite Transparency
Similar to their colors, Crystal Quartz and Fayalite 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, Crystal Quartz is Not Available while Crystal Quartz is Not Available in appearance.
