An aesthetic mineral association showcasing a rare combination of crystalline apophyllite and black stilbite. Fan-shaped clusters ("bundles") of black stilbite grow directly on the apophyllite. Stilbite is characterized by a very dark, almost black color, which is the result of dense inclusions of iron oxides. Main features: Rare variety of black stilbite, strong black-and-white contrast, excellent morphology. Condition: Good - the main crystals of apophyllite are preserved, and the stilbite clusters have retained a pearly luster at their tips.
