Care of Pyrite Specimens
Pyrite, especially the sharp edged cubes from Spain and other localities, is very easy to chip if touched to a hard surface.. It is relatively hard but brittle. To shine up a Pyrite specimen, plain old toothpaste and a toothbrush are fine. After it is rinsed, it is good to rinse in baking soda water, and then spray with rubbing alcohol to avoid water spots when dry.
