About this specimen

A group of quartz points has been swallowed almost whole. Psilomelane has grown over the prisms as a sooty, finely beaded black crust following every face and edge until the cluster reads as charcoal sculpture. Two terminations escaped: one at the summit, smoky and glassy, one at the lower right, water-clear and sharply faceted, the only bright breaks in the black.

Psilomelane is the old field name for hard botryoidal manganese oxides, and it arrives late in a pocket, settling onto whatever crystals already stand there. That is what makes this specimen legible: quartz first, manganese second, the order written on the piece. The coating is hard at Mohs 5 to 6, but its beaded texture holds dust and water dries as pale spotting — use a dry brush.

Small and upright at 5.8 × 3.8 × 5.1 cm and 75 g, it is a miniature for close looking. It comes fixed to a clear acrylic cylinder that lifts the black cluster off the shelf and lets both quartz tips catch light. Both this description and the images were made from the specimen itself.
