A complex and beautiful specimen with thousands of details. Hard to catch on photo.

Aragonite is a carbonate mineral and ranks among the three most prevalent natural crystal forms of calcium carbonate (CaCO3), alongside calcite and vaterite. It is produced through both biological and physical processes, notably through precipitation in marine and freshwater settings.

The crystal structure of aragonite is distinct from that of calcite, leading to a unique crystal morphology characterized by an orthorhombic system and acicular crystals.

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.

Quartz is a robust crystalline mineral made up of silica, or silicon dioxide. Its structure consists of a continuous arrangement of SiO4 silicon-oxygen tetrahedra, where each oxygen atom is shared between two tetrahedra, resulting in the chemical formula SiO2. This classification places quartz as a framework silicate mineral in terms of structure and as an oxide mineral in terms of composition. It ranks as the second most prevalent mineral in the continental crust of Earth, following feldspar.
