Ferberite

Item Description

A great display specimen featuring a tabular, jet-black, striated Ferberite crystals with beige Calcite and golden Muscovite. Panasqueira produced some of the most impressive and attractive Ferberite specimens extant, and pieces like this remind collectors that it is becoming increasingly difficult to obtain good specimens from this now defunct locality. The largest Ferberite measure up to 4.0 cm. A good looking piece for a "black rock". Valued at $950.
