This specimen is part of a vug, lined with small sparkling analcime crystals, hosting stilbite and calcite. The stilbite crystals are sharp and lustrous, with very well-defined terminations. The calcite crystal is a rhombohedron, enclosed within the vug by analcimes. The calcite is well-defined, with low lustre. In excellent condition, no damage. Stands perfectly for display as photographed. A nice combination of these three minerals.
