hackmanite

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.

phosphorescence

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.
