Siderite w/ Pyrite (uncommon combo) Ted Bartels Coll.

Item Description

Siderite is a signature species from the well-known coal mines at La Mure. This is a striking and sculptural mounded 360-degree jackstraw cluster of lenticular oxide-coated orange siderite crystals. The prisms are richly and preferentially peppered with sparkly, tiny brassy pyrite crystals, an uncommon accessory. Choice and pristine combination material from the Ted Bartels Collection.
