Comment: This piece came to me marked as Tsumeb. I have my doubts, but this piece is so unusual it warrants a close look. The white calcite coating is a tightly intergrowwn series of lamellar acute rhombohedral crystals. The orange latticework is now quartz and what it replaced is a mystery.
Minerals: Calcite (CaCO3) Quartz (SiO2)
