Onyx is a mineral and a type of cryptocrystalline silica mineral. Chemically, it has the formula silicon dioxide (SiO2) and shares the same chemical composition with other silica minerals such as quartz, moganite, tridymite, and cristobalite. Onyx often features white or colored stripes or patterns ..

As it is known, agate stone is a group of stones derived from the combination of quartz and chalcedony family. Therefore, this stone is also known as banded chalcedony. It is usually banded in light blue layers, banded with brighter blues, whites and brown threads. It is a valuable natural stone. Sp..
