Agate
It is a cryptocrystalline variety of silica (SiO2). The successive layers of the agate, finely zoned, are of varied colors. It fills the cavities of eruptive rocks (geodes). Agate is a mineral which was used to make jewelry in Antiquity. It is currently used for the manufacture of utilitarian or decorative objects: table tops, vases, boxes, candlesticks, ashtrays, bowls, paperweights in particular. Thanks to its hardness and resistance, agate is also used by various industries.
