Refractory Gold Ore Quartz Crystal Specimen | Specimen 4

Refractory Gold Ore Quartz Crystal Specimen | Specimen 4This refractory gold ore specimen is being sold as a geological and mineral display piece due to the quartz crystals that formed within fractures created during ancient hydrothermal explosion events. These explosive hydrothermal processes fractured and brecciated the host rock, creating open cavities and fracture zones that were later filled by silica rich fluids, allowing quartz crystals to grow throughout the rock. The specimen contains sulfide rich
