QUARTZ GREEN (large cabinet)

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.

This specimen was acquired around 1985, coinciding with the early days of the internet when information on the Chinese practice of coloring minerals or synthesizing them in laboratories was scarce. Subsequently, we identified this specimen as a significant example for your collection, serving as a valuable reference. The key distinction between this specimen and naturally occurring green quartz is that the latter exhibits uniform green coloration throughout, whereas this specimen shows color only on the surface and within the cracks. Today, the market is flooded with artificially created minerals that are often misrepresented as genuine. If something appears too perfect, it is likely not authentic or natural.
