Onyx is a type of chalcedony (a cryptocrystalline form of quartz) with a long history of use in the decorative arts. It was very popular in Graeco-Roman times and is often carved or made into beads. Onyx is the birthstone of the astrological sign of Leo.

Comprised of pure carbon in an alternate structure to the black graphite most associate with the element, diamonds have a host of unique qualities. An interesting one is that they will vanish (oxidising to carbon dioxide) if heated to a high enough temperature.
