Large Amethyst Crystal Geode – 20.06 lb | Natural Uruguayan Purple Specimen

A Visually Layered 20.06 lb Natural Amethyst Geode from Artigas, Uruguay

This 20.06 lb natural amethyst geode from Artigas, Uruguay is a visually layered collector specimen that tells its own geological story. The upper crystal bed is packed with large, brilliantly faceted amethyst points in rich purple, transitioning naturally toward a lower zone of elongated white and lavender quartz formations — a rare gradient effect formed entirely by nature over millions of years.

The contrast between the dense purple crystal cluster and the translucent quartz base creates a depth and visual complexity that sets this piece apart from standard amethyst specimens. The exterior reveals smooth, organically polished chalcedony, showcasing the full cross-section of how this geode formed inside its basalt host rock.

The flat-cut base allows the piece to stand securely without any support. At over 20 lbs, it delivers substantial presence as a floor display, shelf centerpiece, or luxury décor statement. One of a kind.
