It is distinguishable from native gold by its hardness, brittleness and crystal form. Natural gold tends to be anhedral (irregularly shaped), whereas pyrite comes as either cubes or multifaceted crystals. Chalcopyrite is brighter yellow with a greenish hue when wet and is softer (3.5â4 on Mohs' scale).Arsenopyrite is silver white and does not become more yellow when wet.t is distinguishable from native gold by its hardness, brittleness and crystal form.
