Description  Blue color is due to cyprine (the copper-bearing variety of vesuvianite). The chocolate brown mineral is diopside, and the light brown mineral is andradite. Hydrothermal willemite intergrown with the other minerals is the cause of the green fluorescence; in many specimens such willemite is not at all visible in daylight.
