Bright, multicolored specimen that is very phosphorescent. Nicely tenebrescent sodalite (hackmanite) fluoresces bright orange under longwave.

hackmanite and calcite under midwave uv light


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.

calcite, hydrozincite, aragonite, diopside specimen under UV light

Long Lake Zinc Mine - Ontario Canada

The sun was slowly setting so we made dinner and relaxed a while (amazing how slowly the sun sets when you're waiting for it). Once it got dark collected started in earnest. The first thing you notice is the bright blue hydrozincite everywhere on red calcite. All of the small rocks glow. We proceeded to check out the large boulders laying around on the surface and quickly determined that dozens of prior collectors had done the same. That's why they're still lying around.
