An elongated cavity is lined with a crystallized surface of lustrous light green Prehnite, on white Prehnite from the Dean Quarry, Lizard, Cornwall. At the centre of the Prehnite cavity is a divergent cluster of prismatic white Stilbite epimorphs after Natrolite. Later lenticular micro-crystals of colourless Calcite are scattered over the Prehnite, and epimorph. A classic specimen from the 'Zeolite' vein.
