Tree Agate Tumblestone
Tree Agate History
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 name agate itself harkens back to antiquity and the Achates River in Sicily where agates are thought to have been found. At least 3000 years ago, the Egyptians were making seals, rings and vessels from agate stones. Agate was not just a decorative stone and was long used as talismans in Egypt, Greece and India.
Tree Agate Metaphysical Properties
Just as a dappled forest may bring calmness, so it's said tree agate brings a sense of peace and inner tranquility to wearers. This gemstone helps individuals look inside for self-examination, which also may result in a calm demeanor. Agate in general is said to be a stone that promotes inner stability, making tree agate an amplified version. Tree agate is also believed to boost the immune system and balance water in the body.
Agate gemstones in general are believed to have a quiet energy associated with the heart chakra. Agate strengthens relationships, promotes composure and offers a warm, protective quality to the wearer.
Tree Agate Geological Properties
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.
