Rare blue Agate - rock crystal geode on stand Geode - Height: 190 mm - Width: 130 mm- 830 g

Blue agate is a variety of chalcedony known for its beautiful blue hues and fine banding patterns. This specimen is a rare rock crystal geode, meaning it is a hollow rock lined internally with well-formed crystals, often quartz. Agate geodes stand out because of their aesthetic appeal combining the agate's colorful exterior bands with the sparkling crystal lining inside. Mounted on a stand, this specimen is well-suited for display, showcasing the contrast between the polished agate exterior and the raw crystals within. With dimensions around 190 mm in height and 130 mm in width, and weighing 830 grams, it is a moderately sized geode good for decoration or collection. Agate forms in volcanic and metamorphic rocks, where silica-rich fluids fill cavities over thousands of years, resulting in characteristic layers of microcrystalline quartz. The blue coloration is caused by trace elements or structural features within the agate. Collectors value agate geodes both for their visual charm and as examples of geological processes.
