WILLEMITE FLUORESCENT FRANKLIN 004
A stunning specimen of Willemite Fluorescent Franklin 004 showing off the brightest fluorescence of all natural minerals Willemite. This rare special specimen is short and long wave fluorescent. The dark grey metal shown in the natural light photos is Zinc ore Franklinite. The white mineral is Mangano Calcite which in this case shows BIP Brief Intense Phosphorescence. Pics taken with shortwave, longwave, and sunlight. Very cool stuff and this is one of my very favorite rocks. To view this spectacular specimen you will need a UVC Shortwave Lamp and UVA Longwave Lamp. Make sure you wear safety glasses. Willemite Franklinite Calcite is also known as the Christmas Tree Rock for the colours Green and Red. This is a quality collectable specimen with wow factor.
