Pyromorphite, Bunker Hill Mine, Kellogg, Idaho

This little specimen set off a fire storm last summer, and the current pyro craze on eBay has its origins with this little guy.

I had read that pyromorphites sometime fluorescenced so we gambled on a small, natural light piece on an online auction. We won! Yeah! But when it arrived, nada. No glow in shortwave or longwave. Bummer.

A few weeks (or months) later, on a whim, we hit it with midwave and it exploded in color. We were stunned. Who knew there was a mineral that pretty much only fluoresced in midwave? Certainly not the experts! Leave it to the ignorant novices to do a little research and hope for the unexpected.

As mentioned, this is a thumbnail piece, and shown in midwave and natural.
