Dendritic Fossil Ocean Agate is not banded like other Agates, and therefore is not an Agate in the strictest terms. Rather than banding, this Agate has branch-like inclusions of iron or manganese, primarily in black or golden brown, within the colorless to milky white stone. Dendritic Agate is known as the Stone of Plentitude, believed to bring abundance and fullness to all areas of life.
