Pyrite has long been valued as a strong protection stone that shields the wearer from negative energy as well as environmental pollutants. Thus, this stone helps promote physical well-being as well. Stimulating the second and third chakras, pyrite enhances strength of mind and willpower. Pyrite is also sometimes considered to be lucky, attracting wealth and abundance. Though not a birthstone, pyrite is most commonly associated with the zodiac sign of Leo.
