Pyrite:  FeS2

Named in antiquity from the Greek “pyr” for “fire”, because sparks flew from it when hit with another mineral or metal (piezoelectricity).
The mineral pyrite, or iron pyrite, also known as fool’s gold, is an iron sulfide which has the chemical formula FeS2. This mineral’s metallic luster and pale brass yellow hue give it a superficial resemblance to gold.

Calcite: CaCO3

A very common and widespread mineral with highly variable forms and colours. Calcite is best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent cleavage in most varieties.  Named as a mineral by Gaius Plinius Secundus (Pliny the elder) in 79 from Calx, Latin for Lime.

Quartz: SiO2

Quartz is the most common mineral found on the surface of the Earth.  A significant component of many igneous, metamorphic and sedimentary rocks, this natural form of silicon dioxide is found in an impressive range of varieties and colours.  There are many names for different varieties:  Cryptocrystalline varieties of quartz are listed separately under chalcedony and include agate.
