Large Semseyite & Galena w/ Siderite (classic locale)

Item Description

Semseyite is an uncommon Pb-Sb sulfosalt. The historic sulfide Herja Mine is noted for outstanding specimens. This impressive large combination sulfide ore specimen hosts scattered pretty and sculptural rosettes of semseyite blades, to 3.0 cm, among a total covering lustrous to matte-finish, melted-look galena cuboctahedrons. Worm-like or isolated spherical aggregates of tiny tan to brown siderite rhombs are a stark and classic contrast. The underlying matrix of this large plate is granular sphalerite. Rich and hefty sulfide ore at 7.9 pounds or 3.6 kilos mass.
