A nice piece of gemmy blue sodalite. The blue sodalite on this piece is very tenebrescent and changes color when exposed to UV (SW), darkening to a light purple - a unique hue compared to other Greenland sodalites due to the natural blue coloring. Under SW it starts out orange but quickly shifts to a rusty color due to the tenebrescence (see animation below to view the tenebrescent change).

The natural color is a beautiful blue - one of the only blue sodalites which is strongly fluorescent, not to mention slightly tenebrescent.

Many Greenland blue sodalite specimens also contain steenstrupine - a uranium crystal found in Greenland. It is less radioactive than your kitchen's granite countertop, but still a sought after mineral.

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.
