The purple ussingite on this piece fluoresces a very rare green color under UV. Ussingite from Ilimaussaq has three possible states: it can be non-fluorescent, fluoresce orange just like sodalite, or can fluoresce green as in this piece. The green fluorescing variety is by far the rarest. The rare green fluorescence comes from mixing with chkalovite. When ussingite fluoresces a more common orange, it is due to being mixed with Sodalite. The black crystals are non-fluorescent arfvedsonite.

There is tugtupite and polylithionite throughout the specimen as well..

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.
