Beautiful dark amethyst geode with large crystals of the highest quality

A dark amethyst geode from Uruguay with large individual crystals and a deep violet premium coloration. The open geode presents a compact wall of clearly formed violet crystals growing inwards.

Uruguayan amethyst crystallizes in volcanic geodes of the Arapey Basalt Formation. This material is considered the darkest, most deeply violet-colored amethyst variety worldwide. The premium classification evaluates color intensity, crystal clarity, and cavity geometry.

Large individual crystals indicate exceptionally long growth phases with stable solution conditions. The Uruguayan deposits in Artigas and Salto provide this material at the highest quality level.

Amethyst is the violet variety of quartz. The coloration is caused by iron substitutions in the crystal lattice and by natural irradiation in the host rock over long geological periods.

A well-balanced gallery dimension, which makes the geode readable from multiple viewing angles. The combination of block size, premium color, and large individual crystals is rare in the collector's market.
