Petrified Wood Handstones from Madagascar
Petrified Wood
Petrified wood occurs when wood becomes fossilised over a long period through the process of permineralisation, where organic material is replaced by minerals such as quartz. The original wood pattern is usually well preserved in the process, creating the recognisable wood texture in stone.
It occurs worldwide in areas with volcanic activity or rich in siliceous water, such as in the United States (Arizona), Indonesia and Madagascar. Its chemical composition is usually SiOâ‚‚, as it consists mostly of quartz. Its hardness is around 6.5 to 7 on the Mohs scale.
Popular varieties are distinguished by colour and origin, such as red-brown petrified wood from Arizona and black petrified wood from Indonesia.

Hand stones
Hand stones are our largest, tumbled and smoothly polished (precious) stones that often sit very well in the hand, which immediately explains the name. Drummed, this size is also called a palm stone or jumbo stone. Often these stones are extra polished or ground after tumbling for a beautiful end result. Despite this consistency, it remains a natural product, so variations in shape, colour and pattern can always occur. This can vary from one type of stone to another.
Generally, handstones have a size between 4 × 3 × 2 cm and 6 × 5 × 3 cm. Almost all our handstones come from Madagascar, where they are carefully selected and processed. The product photos give a good impression of what to expect. Hand stones are sold per 100 gr (1x), with a minimum order of 500 gr (5x).
