Awesome "geode" of basalt lined with light green translucent botryoidal prehnite studded with "puffballs" of acicular okenite, with translucent very light yellow squarish calcite crystals and sparkling tiny clear quartz crystals. The combination is very aesthetic and conjures up the image of an amazing crystal cave. No damage. Measures 12 x 8 x 7 inches (30.4 x 20.3 x 17.8 cm). From the Nasik area, Maharashtra State, India. Weighs 20 pounds.
