Some people call this crystal "Fool's Gold," but don't be fooled. Pyrite is a powerful healing stone and symbol of luck and prosperity. It resonates with fire energy (and can actually be used to start a fire when struck against metal), making it great for calling in more vitality, self-confidence, and boldness. Pyrite is also protective, shielding the auric field against negative energies and psychic attack. And it's helpful in re-balancing the power dynamics if you have a crappy partner who's overbearing or controlling.
Tumbled stones range from 1/4”-1” in size.
