A cluster of BIG smithsonite crystals from the greatest worldwide mineral locality, Tsumeb! These crystals measure up to TWO CENTIMETERS across, which makes them rare not just for Tsumeb, but for anywhere! But the fact they ARE from Tsumeb makes the specimen just that much more desirable. The color is hard to describe, but accurately depicted in the photos - similar to the color of a German pyromorphite from Bad Ems, if you are familiar with those. From the well-known California collection of Charles Hansen.
