Agate is a variety of Chalcedony, a renowned variety of quartz composed mainly of silica. It is a hard stone that varies in color from light brown to creamy white. It has a grainy surface and is covered with patterns in the form of bands, arcs or knots, which are due to the presence of colored minerals (iron oxide, sphene or manganese) or fossils suspended in the rock. Agate forms in river beds, when suspended materials settle and accumulate in the crystalline rings of quartz source rocks. It can also form in volcanic holes, in sedimentary layers or due to cracks in metamorphic rocks. Agate is one of the most popular and abundant minerals in the world. It is often used as a gem or an ornamental stone. It is also frequently cut to create earrings, pendants and stone jewelry. It is also used in the paper industry, as quartz is a very effective abrasive material. In addition, Agate is a common mineral in lithotherapy, where it is used for its reassuring and calming properties.
