Strike it rich with our box of fools gold! Pyrite, or fools gold, as it is known, have fooled a lot of prospectors looking for real gold. Brassy yellow in color and chunky in appearance, it is a brittle metallic mineral that is more than 50% sulfur in composition. Our pyrite pieces come in a clear plastic display box. They would make an excellent party favor. Box measures 1.5 x 2 inches. Not for children under age 3.
