Onyx Stool

Onyx is mostly composed of quartz. Quartz is made of silicon dioxide, also known as silica. It is believed that the silica originated in volcanic ash and settled over the buried trees. Over the years, the wood absorbed the mineral and crystallized. Impurities in the quartz, including iron, carbon and manganese are also found in petrified wood.
