The incredible deluge of world-class minerals coming out of China is in great part thanks to their explosive economic growth of the last few decades: this has led to the opening of mines and the exploitation of new mineral veins to extract ores. The need for the semi-metal Antimony, which has a wide number of uses in modern industry, has resulted in a series of deposits being discovered. Some of these deposits have open caverns and fissures where perfect blades of Stibnite, an antimony sulfide that occurs commercially as antimony ore, grow out from open pocket walls. Miners preserve such specimens, like this one that became a part of the Kennedy collection, for the collector's market, saving many exceptional specimens from the crusher. This incredible cluster of countless mirror-luster crystals stretches to 25 centimeters, with most of the crystals being perfectly terminated. This specimen comes with a custom acrylic base.
