Well, all jokes aside, you can certainly see why they called this the Blue Ball Mine. This is an adorable geode of solid azurite, with tiny sparkling crystals in the middle, accented with pretty green malachite. These are very hard to get now This one came from Arizona collector/dealer Evan Jones. 2.7 x 2.4 x 1.1cm, 2.7 x 2.3 x 1.4cm
