though it's also an industrial mineral

The two minerals are interpreted as near-synchronous hydrothermal precipitates

The occurrence of agate as multi-columnar clusters is uncommon

Stibnite‑Calcite‑Selenite Epigenetic‑Growth Specimen B mineral Dimension:3*2StibniteCalciteSelenite EpigeneticGrowth Specimen from Weishan YiHui Autonomous County, Dali, Yunnan Province, China Primary stibnite crystals crystallized first within the hydrothermal vein. Orangetoned scalenohedral calcite later precipitated and encrusted the stibnite matrix. Finegrained fibrous selenite fully covered the calcite layer afterward. Exposed calcite crystals are manually chiselled out from the outer selenite layer. This threestage
