A Gorgeous, High-Grade Galaxy Amethyst Geode with Rare Inclusions
▫️ Description
Magnificent, rare and colorful, this Amethyst Geode features a stunning multi-colored, deep purple Amethyst crystals on a perfectly cathedral shape geode. Imagine this geode enhancing your space, offering a calming energy.
What first catches the eye in this geode is the variety and beauty of its Amethyst crystals. At the top, a sparkling purple galaxy druzy resembles a night sky, beautifully accented by elongated flower formations naturally filled with golden goethite inclusions—reminiscent of shooting comets.
On the bottom half, a crown-like formation of large Amethyst points has uniquely taken shape. This rare formation is found in only a handful of mines, making this geode truly one-of-a-kind. Within and around this "crown," additional calcite crystals and smaller Amethyst points with unique inclusions further enhance the specimen’s beauty.
Overall, this geode stands out not only for its vibrant banded agate but also for its exceptional variety of mineral inclusions, such as Goethite (Cacoxenite), Calcite, and other fascinating mineral formations.
Perfectly sized at just over 21 inches tall and weighing 39 lbs, it’s ideal for display as a centerpiece or addition to your collection. The geode's base consists of a thin Basalt layer, securely reinforced to protect and showcase its intricate and delicate natural structure.
Ethically sourced directly from Ametista do Sul, Brazil—renowned for producing some of the world's finest Amethyst—this specimen brings peace of mind along with exceptional beauty.
This high-quality Amethyst geode is sure to become a treasured highlight in your collection or decor. Please view the photos for additional details, and feel free to message us with any questions or special requests. 🤍
