We have run out of stock for this item.
Huge specimen of minor phlogopite, calcite, scapolite (marialite), hauyne or perhaps massive afghanite.
Lots of areas appear to be homogeneous blends of minerals. For example, under SW the bluish fluorescence in the lower left appears to be perhaps diopside, or possibly gonnardite. But under LW the blue fluorescence disappears and is replaced by dark orange from what is likely hauyne.
Under MW a large area of dull blue/white fluorescence towards the upper left.
First, an animation showing the difference between the UV flashlight we recommend (365nm filtered UV flashlight) versus unfiltered 395nm UV flashlights we see many folks carrying around at shows. So. much. visible purple light. We selected a bunch of rocks as a demonstration. Took pictures of them under his flashlight without the filter and then with the filter.
A major component of rock collecting (for us) is simply getting out in nature. A buddy dragged us out to a very remote area here in middle Tennessee to hunt for fluorescent green agate. Since we consider ourselves pure "Glow Hounds" we weren't anticipating any glow rocks, just the beauty of the area, but we brought our UV lights anyway.
