One of the most interesting properties of pyrite is its ability to generate sparks when struck against a hard surface. This property has made it useful in creating fire in ancient times. However, it is important to note that pyrite should not be used to start fires as it releases harmful sulfur dioxide gas when heated.
Pyrite is also known for its protective qualities. It is believed to shield the user from negative energies and promote a sense of grounding and stability. Additionally, pyrite is said to enhance creativity and intellectual pursuits, making it a popular stone for artists and academics alike.
