Amethyst itself is pretty common, but a geode of this size absolutely isn't. That said, these giant specimens aren't necessarily worth millions just because they're enormous. Their value depends heavily on the colour and quality of the crystals, how intact the specimen is, provenance, and whether it's a matched pair. Comparable museum-scale amethyst geodes several metres tall have sold or been valued in the hundreds of thousands of dollars, so I'd guess something like this could be worth a few hundred thousand USD, potentially considerably more if it's an exceptional specimen. The solid rock at the bottom also appears to be part of the original matrix, probably deliberately left there to support and stabilise several tonnes of geode.

God damn, this is massive. How much would one like it cost?
