What makes this piece rare

Unlike a closed cathedral geode, this is an open face amethyst geode — the full crystal cavity is exposed, making the interior visible from multiple angles. The wide, low profile suits shelves, console tables, and display surfaces where a tall cathedral would overwhelm the space.

The defining secondary feature is the amethyst druzy cluster with calcite inclusion — a white mineral formation that grew inside the amethyst cavity over millions of years as mineral-rich fluids moved through the rock. Structurally distinct from the surrounding crystal bed, it is the kind of geological detail that elevates a beautiful piece into a true collector's specimen.

This dark purple amethyst cluster from Uruguay carries the dense, saturated color Artigas is known for globally — deep violet points of exceptional clarity, sourced from one of the world's premier amethyst-producing regions.

Display and placement

At 28.72 lb and 12 inches wide, this amethyst cluster display piece is proportioned for shelves, console tables, credenzas, and low plinths. The open formation reads beautifully from above and from the side — ideal for spaces where a cathedral's height would be too dominant.
