Large Brazilian Amethyst Geode Cathedral

This striking mineral specimen features a substantial vertical section of a basaltic geode originating from Minas Gerais, Brazil, with an interior central cavity lined in a rich, macrocrystalline amethyst druse. The pristine quartz crystals exhibit deep purple saturation with vitreous terminations that seamlessly transition from a soft lilac base to concentrated, dark violet tips. Structurally layered, the core mineral cavity is framed by an inner ring of translucent chalcedony and an outer, naturally textured rind of dark green celadonite-coated basalt carved with a flat-cut base for upright presentation. This lot sits within a complete documentation package, accompanied by its original typed mineralogical data sheet alongside an official retail informational provenance slip from the Silver Eagle Gallery of Highlands, North Carolina, and Naples, Florida.
