Quartz Geode Half
This item is a natural geological specimen, specifically identified as a geode half, likely composed of quartz crystals within a chalcedony or agate outer shell. Its physical characteristics indicate a palm-sized piece, measuring approximately 3-5 inches in its largest dimension, fitting comfortably within an adult hand. The exterior showcases a rough, natural rock surface, predominantly greyish-brown with visible banding of blue-grey and off-white translucent layers, characteristic of chalcedony or agate, particularly noticeable near the break point. The striking feature is its interior cavity, densely lined with numerous small, sparkling crystals. These crystals appear to be drusy quartz, presenting as clear to milky-white, well-formed facets that reflect light. No obvious manufacturing details are present, as this is a naturally formed object. The visible condition appears excellent for a natural specimen; the crystal formation seems robust with no apparent damage or significant wear beyond what is expected from a naturally fractured geode. There are no signs of repair or artificial enhancements. The quality indicators point to a good specimen due to the density and clarity of the crystal growth. Its estimated age is geological, having formed over millions of years.
