Large Dark Amethyst Cluster 21.71 | lb Deep Black Druzy Uruguayan Geode

A Sculptural Amethyst Cathedral Geode from Artigas, Uruguay

This 21.66 lb natural amethyst cathedral geode from Artigas, Uruguay is defined by its tall, tapered form — the classic cathedral silhouette that collectors and interior designers seek for its sculptural presence. The crystal surface is covered in densely packed, small-to-medium amethyst points with a luminous silver-purple shimmer, creating a sparkling druzy effect across the entire face.

At the center of the specimen, a large natural white quartz formation emerges organically from within the crystal bed — a striking geological inclusion that contrasts beautifully against the purple and adds rare visual complexity to the piece. A secondary quartz and agate band runs along the lateral edge, revealing the full layered history of this specimen’s formation.

The flat-cut base ensures stable, stand-free display. At nearly 22 lbs, this cathedral stands as a genuine room anchor — elegant in a living space, commanding in a collector’s cabinet. One of a kind.
