Pale green colored Prehnite formed over Anhydrite crystals which subsequently dissolved leaving hollow, well formed casts. The Prehnite has the appearance of rounded, stalactite like growths. Scattered across the Prehnite are thin, brown colored Stilbite crystals which are translucent and have a glossy luster. Of particular note, are the white to clear colored Calcite crystals on the bottom of the specimen. Many of these crystals have a long, narrow habit with sharply pointed terminations.
Condition: Good
Flaws: A few of the Stilbite crystals around the edges of the specimen are incomplete.
