Black Agate Thumb Stone

Black Agate
Protects against negative energies
Attracts good fortune and promotes goodwill
Increases concentration and clarity
Aids in overcoming flaws, fears & loneliness
Instills a sense of strength and courage
 
Please note:  These are much smaller and thinner than the other thumb stones I have and take to shows.  That's why I take a picture next to a coin.
