Geodes are spherical rocks that contain hollow cavities lined with crystals. The name geode comes from the Greek word Geoides, which means "earthlike." These geodes can be hollow, semi-hollow or may be filled solid with quartz and agate (solid ones are referred to as nodules). This cut and polished geode is mesmerizing with its unique markings... from gentle and calming hues to colorful and stunning tones.
