WILLEMITE FRANKLINITE CALCITE LARGE
A stunning specimen of WILLEMITE FRANKLINITE CALCITE LARGE size showing off the brightest fluorescence of all natural minerals Willemite. This rare special specimen is short and long wave fluorescent and phosphorescent. Showing a thin vein of Willemite on pics. Willemite (Green) is associated with Zinc ore and Zinc mining. Shown in pics with short wave UV light. In the light of day it looks like a rock with little chunks of grey metal in it. This specimen is also phosphorescent, like when I take away the SW UV light the Willemite still glows for some seconds. Very cool stuff and this is one of my very favorite rocks. To view this spectacular specimen you will need a UVC Shortwave Lamp. Make sure you wear safety glasses or glasses. The Metallic looking octahedral crystals of Franklinite are shown well in the daylight pics. Some red Zincite can be seen too.
