Magnetite and Euclase Optic Character

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

Magnetite and Euclase Transparency

Similar to their colors, Magnetite and Euclase 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, Magnetite is while Magnetite is in appearance.
