A Museum-Grade Amethyst Cathedral
Weighing an extraordinary 619 pounds, this massive amethyst geode cathedral is a true collector's centerpiece. The deep violet amethyst crystals line the interior cavity in dense, sparkling layers, punctuated by scattered calcite formations that catch the light in warm golden hues. 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.
