Cinnabar is named after Greek "kinnabaris", the ancient name for the mineral; possibly from Arabic "zinjafr" or Persian "zinjifrah", dragon's blood, probably alluding to its colour.

Cinnabar usually occurs as masses or crusts. Well-formed crystals are very rare. The material has cochineal-red colour with adamantine to metallic lustre.

Clear cinnabar crystals are faceted into spectacular stones. Massive material is used for cabochons.
