The earthly treasure Moss Agate stone is a semi-precious variety of chalcedony, known for its moss-like inclusions and intriguing mottled patterns of black, cream, and green-gray. It is considered to be a stone of a new beginning that can be found all around the world; however, some of the highly prized mining locations include Australia, Uruguay, the United States, Brazil, India, central Europe, and Russia. Since antiquity, the Moss Agate Pendant has always been cherished as a good luck amulet or talisman believed to bring a bountiful harvest and protect against black magic, evil thoughts, or bad karma.
