Tree Agate is a form of Dendritic Agate. It is a chalcedony with dendrite inclusions of moss colored green minerals. Tree Agate is an unusual agate as it is usually opaque white and doesn't have the banding usually common in chalcedonies that are named "agate".
Dendritic inclusions are usually fern, tree or branch like. It is named dendritic or dendrites from dendron, which means "branch like" in Greek. Dendrite inclusions are formed due to the presence of manganese and iron oxides. Often Tree Agate is confused with Moss Agate, but Moss Agate inclusions are more mossy shaped or bush like inclusions.
Agate is a type of chalcedony, usually at least slightly translucent and banded or with inclusions. It forms in concentric layers in a wide variety of colors and textures. Each individual agate forms by filling a cavity in host rock. Agate has a hardness of about 7 on the Moh's scale. The name is derived from its occurrence at the Achates River in southwestern Sicily.
