Mottramite with Calcite (ex Brian Kosnar Collection)

Item Description

A classic specimen from Tsumeb of deep olive-green Mottramite forming botryoidal aggregates with the classic "greasy" luster which are overgrowing and associated with white to colorless Calcite crystals on matrix. Some of the Calcites are nearly water-clear, and the overall balance and aesthetics of the piece make it a good cabient size specimen from this most renowned of localities. I have photographed the Mottramite under the microscope to better illustrate the quality. These classic specimens are very difficult to find on the market, and certainly these have to be some of the most distinctive and impressive Mottramites extant!
