Hackmanite mine ⛏️
Hackmanite is colour changing variety of sodalite. That effect is called tenebrescence. Material in Khibiny and Greenland have best material in the world in my opinion. Afghani material is good too, but it can't be found in such big masses. I've been dreaming whole season about finding a new vein of that material and finally I found something really good. Stay tuned for some polished things from that find. All credits to @wild_nrocks
