Mordenite Spear Cluster x Calcite

This is a unique cluster of mordenite “spears”, which formed into a large spherical formation. Atop the tips are clusters of vibrant yellow calcite crystals that have an exceptional glow under UV light. This was a small find and these are very hard to come by, especially in this large size.
