Group of clear to yellowish milky quartz crystals radiating from a metalliferous substrate, mainly pyritic. Some of the crystals tend towards a sceptre quartz habit, characterized by a second generation of crystals growing on top the earlier generation, which they often outsize. Sample size is 15 cm top to bottom. | |
