Note 1: Petrified wood comes from petrified wood, in which all organic materials have been replaced by minerals. As a result, the structure of the wood has been nicely preserved. Petrified wood is found in a wide variety of colors due to variation in the deposits of minerals such as manganese, iron and copper. Quartz is colorless, but when iron is added, for example, crystals with a red or yellow color are formed, as shown in the list below: carbon black Cobalt - green / blue Chrome - green / blue Copper - Green / Blue Iron Oxides - Red, Brown, Yellow Manganese - Pink / Orange Manganese Oxides - Black Silica - white, gray Operation: Petrified wood is a grounding and soothing stone with a soft effect.

Petrified wood is a type of fossil: it consists of fossil wood, in which all organic materials have been replaced by minerals (usually silicates, such as quartz), while preserving the structure of the wood. The process of petrification takes place underground, when a tree becomes buried under sediment and can last for millions of years. Groundwater that slowly seeps through the soil deposits minerals where the lignin and cellulose rot. If the deposition goes as fast as the decay process, the shape of the cells is preserved. The smallest details can be saved for eternity. Petrified growth rings and various tissues can be traced down to a microscopic level. Petrified wood has a hardness of 7 on the Mohs scale, the same as quartz. Will be shipped registered and insured Ref: P 22
