These are lovely round Pyrite Crystals from Peru.
Each one measures about 1” inch.
Pyrite is known as a stone of luck, helping to attract abundance, wealth and prosperity to the user, via its creative energies of manifestation, and its encouragement of following one's dreams.
This quality makes Pyrite excellent for grid work and rituals. Pyrite not only deflects negative energies, but also helps to release negative and inhibiting patterns of behavior. Pyrite can enhance one's will during challenging times and supports the action necessary for personal growth and success.
Meditation with Pyrite can encourage greater frequency in moments of inspiration, and its grounding action allows these higher frequencies to be grounded into the physical world.
