Giant 6ft Brazilian Amethyst Geode | Custom Swivel Stand

A Cavity Carved by Deep Time At nearly six feet tall, this giant Brazilian amethyst geode commands presence like an art installation. Indeed, mounted on a custom black swivel stand, it rotates freely — a rare feature at this scale. Ancient lava flows first trapped the gas cavity that shaped this geode, and over millions of years, in turn, deposited quartz along the interior wall. Given the scale of this piece, that process likely ran for an especially long, undisturbed stretch of geological time. After all, conditions like these rarely produce a specimen this size. Consequently, the crystal lining reaches deep and richly saturated throughout — exactly what large-format collectors look for.
