The black color in petrified wood is derived from the presence of pyrite or organic carbon in the soil mineral. Pyrite sparks when it is struck and is called ‘fire mineral’. A completely charcoal black petrified wood piece is rare and it requires a true connoisseur's eyes to appreciate the textural markings in the subtle variations of charcoal black.
