This massive piece of geology-as-it-formed is a masterpiece of nature in and of itself. Malachite in many forms, from massive to stalactites to interesting cup formations. An endlessly explorable, untrimmed vintage large cabinet mineral specimen. Minor damage provides a view of the internal morphologies of the piece, truly remarkable. Tsumeb Mine (Ongopolo Mine), Tsumeb, Oshikoto Region, Namibia. 7.5" x 6" x 7", 7 pounds.
