Hydrogrossular and Pectolite Optic Character
Hydrogrossular and Pectolite optical properties play a significant role while distinguishing these gemstones from each other. These properties are influenced by the Hydrogrossular and Pectolite 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 Hydrogrossular and Pectolite 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.
