the calcite naturally develops its rhombohedral crystal habit

Realgar appears as discontinuous fine veinlets

This three‑stage paragenetic sequence records gradual shifts in hydro‑thermal fluid chemistry and displays a rare zoned‑type over‑growth structure

The zoned internal structure is sharply defined under transmitted light

Purple-rim Phantom Cubic Fluorite 2 china the calcite naturally develops itsFrom Dachangmine, Qinglong, Guizhou Prov., China. Fluorite from Dachang, Qinglong County, Guizhou Province, China. Crystallizing in the isometric system, the specimen forms an euhedral cubic crystal cluster with distinct purple rim zoning (phantom crystal color banding). Individual crystals feature deep violet peripheral margins and translucent off white cores; crystal surfaces bear stepped growth striations. The zoned internal structure is sharply
