7" Polished Agate Obelisk With Amethyst Pocket - Uruguay
This is a 7" tall, polished obelisk made from a portion of an amethyst geode. It features beautiful banded agate that formed as the transition layers between the rock of the geode and the druzy amethyst crystals within the geode. This specimen was collected from the famous amethyst mines in Artigas, Uruguay.
About Uruguay Amethyst
Though Brazil produces a greater volume of amethyst, the material from the Artigas region of Uruguay is renowned for its exceptional depth of color and superb crystal quality. Uruguayan amethyst typically forms in dense basalt flows and develops into richly saturated, grape-purple crystals that are considered some of the finest in the world. Because we import our specimens directly from the mines, we’re able to offer outstanding prices on everything from dramatic geodes to premium clusters and collector-grade crystal formations.

About Agate
Agate is a variety of microcrystalline quartz (chalcedony) that displays translucence and, in some cases, banding. Agate primarily forms when silica-rich fluids fill pockets within rocks and/or fossils, depositing the silica along the walls of the rock. This process can result in banding patterns, as the compositions and impurities of these depositing fluids change over time. These banding patterns can either form as flat layers, creating linear patterns known as waterline agate, or as rounded layers, forming more common ring-like patterns. These patterns depend on the surfaces available for deposition.
