Moss Agate is not banded, and therefore not strictly an Agate in scientific terms but is included in the Agate family. Agate is a variety of Chalcedony, a mineral of the Quartz family.
Moss Agate is said to enhance the mental function of a person by simply improving their concentration, awareness, and diagnostic abilities. It is also an anti-inflammatory stone that assists in healing infections, swelling, flu, colds, as well as reducing fever. It is useful for long-term sickness and revitalisation.
