Petrified wood is a beautiful grounding stone. It helps calm scattered energies. Extra information: Petrified wood is fossil wood in which all organic components have been replaced by minerals. Note 1: Petrified wood is petrified wood in which all organic materials have been replaced by minerals. As a result, the structure of the wood has been beautifully preserved. Petrified wood is found in a wide range of colours due to the variation in the deposits of minerals such as manganese, iron and copper. Quartz is colourless, but if iron is added to it, for example, it produces crystals with a red or yellow color, 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, grey Operation: Petrified wood is a grounding and soothing stone with a gentle effect. It stimulates our connection with the earth and reduces homesickness. That is why we always feel in the right place and at home. The stone calms, creates a pleasant atmosphere and a feeling of well-being. It stimulates a level-headed attitude, concentration and control. Physically petrified wood stimulates metabolism and prevents obesity. Zodiac sign: Aquarius Composition: variable, hardness: 7 & density: 2.6. Petrified wood is a type of fossil: it consists of fossil wood, in which all organic materials have been replaced by minerals (mainly silicates, such as quartz), while the structure of the wood is preserved. The process of petrification takes place underground, when a tree becomes buried under sediment, and can take millions of years. Groundwater that slowly seeps through the soil deposits minerals where the lignin and cellulose rot away. If deposition proceeds as quickly as the rotting process, the shape of the cells is retained. The smallest details can be preserved for eternity. Fossilized growth rings and various tissues can be traced back to the microscopic level. Petrified wood has a hardness of 7 on the Mohs scale, the same as quartz. Will be shipped registered and insured Ref: O -75
