Petrified wood is actually fossil wood of millions of years old. After the death of a tree, the shape and structure of the wood cells are transformed into quartz, usually chalcedony, jasper and opal.
Petrified wood still often has the colours of wood, as various shades of yellow, orange, red, brown and black. Yet there are also other colours, such as green, blue, purple and pink.
There are beautiful pieces of petrified wood with cavities in which amethyst or other quartz crystals have grown. And sometimes the cracks or holes are filled with opal. This is then called wood opal.
Petrified wood can occur in both tropical, subtropical and temperate areas. The most popular are the petrified wood from Arizona and Madagascar, because of their beautiful colours and clearly recognizable wood structure.
