huge stone with many different amethyst geodes

A gigantic block from Brazil featuring many different amethyst geodes. Multiple cavities within a single basalt piece, each lined as its own violet crystal stage.

Multi-geode stones are formed when several separate geode cavities within a single basalt block are filled with amethyst growth simultaneously or sequentially. The individual geodes exhibit different sizes and geometries.

Such constellations are paleogeological documents. Each cavity corresponds to an original gas inclusion in the solidifying basalt, each mineralization phase to a geochemical episode over millions of years. Brazilian deposits in Rio Grande do Sul provide this premium material.

The multi-geode geometry makes the piece a mineralogically instructive display block. A museum-worthy collector's item with documented multi-geode genesis and architectural gallery dimensions, suitable for reception areas or loft presentations.
