Agate is a microcrystalline variety of quartz, a mineral composed of silica, which generally forms in the cavities of volcanic rocks, where silica-rich solutions are deposited in successive layers. These deposits, often of various colors, create the characteristic patterns of agate, ranging from parallel bands to dendritic shapes. The diversity of colors is due to the presence of impurities such as oxides of iron, manganese or other trace elements. The formation of agate is a slow geological process that can take millions of years. Temperature and pressure conditions, as well as the composition of mineral solutions, influence the growth of quartz crystals and the formation of the characteristic agate patterns. From a physical point of view, agate is a relatively hard and wear-resistant mineral. Agate has been used since ancient times as an ornamental stone. It is commonly cut into cabochons to make jewelry, but it is also used to make decorative objects, such as sculptures or vases.
