A truly antique Tsumeb piece from the very earliest workings at the mine, judging by both Carnegie's lifetime and by the nature of the piece. The specimen features a 5-cm (2-inch) reticulated cerussite perched atop heavy matrix. The cerussite looks complete from the front but is actually missing a spoke on the upper-right of the crystal, and this is admittedly visible from the side (hence the low price on such a large and historic Tsumeb rock!).
