One of the most spectacular geode presentations we have ever seen. The internal mineralization features gemmy clear crystals of miniature Heulandite hosting a dozen-crystal ridge of Cavansite, dusted with perfectly spaced rhombohedral clear Calcite crystals. Two windows into the vug provide ample light to the completely natural interior. A truly fine mineral. Wagholi Quarry, Pune, India. 4" x 4" x 2.75", 1.3 lbs
