Bournonite & Siderite on Quartz (classic locale)

Item Description

Brilliant, sharp, metallic-gray, twinned and untwinned bournonite crystals, to 8 mm, are richly and attractively clustered on a contrasting rich covering of lustrous, tan flattened siderite rhombs on the sculptural quartz and siderite matrix. The crystals are so fine and sharp and the piece has multiple display views. This is classic and excellent combination material from this ancient iron mine, that closed in 1965.
