About Tree Agate

Tree Agate is a variety of chalcedony distinguished by its pale, milky background and the branching, moss-like green inclusions that give it its name, rather than the ringed banding most people associate with agate. It forms slowly inside volcanic rock cavities as silica-rich groundwater deposits itself around included minerals, and it has been used and gathered for centuries as part of the wider agate family.
