Description

What a nice piece! The sharp terminated, glossy calcite crystals show a greenish color caused by duftite inclusions and are covered with micro-crystals of smithsonite. The duftite inclusions are not really uncommon for Tsumeb, but the additional layer with smithsonite makes this piece stand out the crowd. Hard to photograph, better in person. No significant damages to report.
