A stunning rosasite, perhaps among best of species for a USA locale, with shocking color and large bubble growths. Rich, fine specimens of this mineral are very rare from ANY world locale, and Tsumeb examples are treasured and valuable/expensive. Here is a choice example, and from the USA! Bob Reynolds had a significant suite of rare and interesting SW USA material, and this was a surprise among them! Bob was a prolific field collector and intellectual collector of so many suites, former Earth Sciences curator of the San Bernardino Co. Museum, and well respected in the field.
