Throughout history and all cultures, Moss Agate has been known as the crystal of gardeners and agriculture. It was considered a miraculous healing stone for tribal priests of the past, giving them power to interact with our human organic system, and was used as a talisman to make warriors strong and victorious. Moss Agate is extremely beneficial as a body strengthener in times of stress. Its steady energies aid those who feel unstable or ungrounded. It is an excellent stone for convalescing after illness, or in recovery from addictions. It enhances mental concentration, persistence and endurance, making it useful as an aid in physical exercise programs. It is clear to milky white, with dendritic inclusions of manganese or iron that has grown into patterns similar to moss or lichen.
