INESITE, PYRITE, QUARTZ (LARGE CABINET)

 Inesite is a hydrous calcium manganese silicate mineral characterized by the chemical formula Ca2Mn7Si10O28(OH)2•5(H2O). This inosilicate mineral crystallizes in a triclinic system and exhibits a Mohs hardness ranging from 5.5 to 6, along with a specific gravity of 3.0. Its name is derived from the Greek word Ίνες (ines), meaning "fibers," which reflects its distinctive color and habit. Inesite is typically found in hydrothermal replacement deposits associated with manganese-rich metamorphic rocks and serpentines. It was first identified in 1887 at the Hilfe Gottes Mine in Dillenburg, Hesse, Germany, and has since been located in several other significant sites.

Pyrite, commonly referred to as fool's gold, is an iron sulfide with the chemical formula FeS2, also known as iron (II) disulfide. It is the most prevalent sulfide mineral found in nature.
