Budget Refractory Gold Ore Quartz Crystal Specimen Lot | 3 Small Hydrothermal Breccia Samples

Budget Refractory Gold Ore Quartz Crystal Specimen Lot | 3 Small Hydrothermal Breccia SamplesThis budget specimen lot includes 3 smaller refractory gold ore quartz crystal samples that did not make the cut for individual premium listings but still display interesting geological features and quartz crystal growth formed during ancient hydrothermal explosion events. These specimens formed when explosive hydrothermal activity fractured and brecciated the host rock, creating small cavities and fracture networks that were later filled by silica
