A Museum-Grade Amethyst Cathedral
Weighing an extraordinary 619 pounds, this massive amethyst geode cathedral is a true collector's centerpiece.

The exterior shell displays the characteristic agate banding of a genuine Brazilian cathedral geode, with its organic, rounded form and natural grey-white casing.
At this scale, this piece transcends decoration — it becomes a presence. Whether displayed in a luxury residence, hotel lobby, wellness center, or private collection, it commands attention and respect in any space it occupies.
