Bright, multicolored specimen that is very phosphorescent. Nicely tenebrescent sodalite (hackmanite) fluoresces bright orange under longwave.
Calcite is very bright red under midwave, dimmer under shortwave. Phlogopite is a butterscotch yellow under shortwave. Diopside is bluish-white. The dim yellow brown under shortwave is possibly richterite.
We prefer displaying this specimen under fullwave (FW) meaning all wavelengths: shortwave, longwave and midwave - as that makes each corresponding mineral pop, but they are respectable under any wavelength.
These pieces are fresh mine-run material. They are not acid washed like most of the specimens found on the market. The sellers in Pakistan use acid to eat away the calcite, revealing crystals embedded in the matrix. This results in an artificial appearance and often eats away at other minerals.
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.
