Alexandrite is a rare gemstone that changes color depending on the type of light it's in. Colors range from a bluish green in daylight to a purplish red in incandescent light.
Usually a facetted cut, the alexandrite is suitable for daily wear with a hardness rating of 8.5 out of 10. Its rarity as a genuine earth-formed gemstone, especially in larger sizes, makes the alexandrite a highly desirable and unique class ring upgrade.
