Moss agate is sometimes called the "gardener's stone" due to its mystical properties of helping ensure a full crop. In addition to a full crop, moss agate is said to bring general abundance, success, and prosperity. It is also said to help one gain peace with extreme or excessive duties in life and brings self-confidence and higher self-esteem. Moss agate is also said to be a metaphysically protective stone.
Green moss agate is said to assist in finding hidden treasure, and be a stone of prosperity.
