Amethyst Zeolite cluster from Brazil. Unique and rare pattern! Natural red, blue, purple and grey colored specimen. You will receive the exact same one from the photos.
Size: Small, 2.65 inches in diameter
🪨 Specimen Details: Primary Minerals: Amethyst (Quartz, SiO₂) with Zeolite (typically Stilbite or Heulandite - hydrated calcium sodium aluminosilicates)
🔬 Geological Context: Amethyst in this formation is typically deposited as a secondary mineral within gas vesicles or fractures in basaltic lava flows, forming under hydrothermal conditions. The zeolite minerals present (often Stilbite or Heulandite) are commonly found in the same environment, crystallizing from mineral-rich solutions at relatively low temperatures and pressures.
