Tree Agate Rough Rock - Per Kilo

Tree agate is also known as dendritic agate. Dendrites are crystal inclusions that develop in foliage or tree branch-like patterns. In tree agate, these dendrites create a beautiful green dappling effect on a white base. This beautiful green and white stone has long been seen as having a deep connection to nature and was therefore viewed as the stone of plentitude by many civilizations. The ancient Greeks associated tree agate with dryads and the stone was sometimes buried in agricultural fields to promote a plentiful harvest.  

The distinctive inclusions that resemble vegetation in dendritic agate are a result of the presence of manganese and iron oxides finding their way into cracks of white quartz as it forms. Tree agate has a hardness of 6-1/2 to 7 with a specific gravity of 2.59 to 2.67. This type of agate is frequently mistaken for moss agate, but these stones have different mineral traces creating the unique green branch-like patterns. Tree agate is most commonly found in Brazil, China, India, Australia, Kazakhstan, Madagascar, Mexico, Mongolia, Namibia, Uruguay and the United States.
