Pyrite is known as fool's gold due to its resemblance to gold and occurs as cubic crystals, but can also form octahedrons. The metallic luster and golden color of pyrite are its distinctive characteristics. Pyrite is a common mineral found in many types of rocks.

Sphalerite is a mineral that belongs to the class of sulphides, more precisely, it is a zinc sulphide, with the chemical formula ZnS. It is mainly recognized as the most important source of zinc. Sphalerite typically occurs as cubic, octahedral, or dodecahedral crystals, but can also take the form of granular or compact masses. Its color varies from brown to black, although it can also be yellow, green or colorless. Its hardness on the Mohs scale is 3.5 to 4, which makes it relatively soft. Sphalerite is also notable for its high optical dispersion, greater than that of diamond, which gives rise to remarkable brilliance when cut into a gem.
