Agate Slices
Each one ranges from 4"-5" in length Stand included Agate is a captivating variety of microcrystalline quartz, known for its intricate patterns and vibrant colors. It is a type of chalcedony, which is a cryptocrystalline form of silica, meaning its mineral crystals are too small to be seen with the naked eye. Agate typically forms within cavities or voids in volcanic rocks or certain types of sedimentary rocks. The intricate banding and patterns seen in agate are a result of variations in mineral content and impurities present in the water. For instance, the presence of iron oxide can give rise to red and brown bands, while manganese may contribute to black or gray bands. The specific colors and patterns are unique to each agate specimen and are determined by the geological conditions and minerals available during its formation.
