Pyrite cubic crystals on marl from Navajún, La Rioja, Spain (size: 95 by 78 millimetres [3.7 by 3.1 in], 512 grams [18.1 oz]; main crystal: 31 millimetres [1.2 in] on edge) Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.

Several of the minerals where a bite test could be diagnostic contain heavy metals. Even gold can be toxic, with repeated ingestion or in impure form. Hardness
For example, gold is sectile but pyrite ("fool's gold") is not. Sectility in metals is a result of metallic bonding , where valence (bonding) electrons are delocalized and can flow freely between atoms, rather than being shared between specific pairs or groups of atoms, as in covalent bonding .
