Minerals / Quartz, Rose var.

Quartz is silicon dioxide SiO2, one of the most common minerals to be found in the Earths crust. There are many varieties of quartz, and this particular specimen is rose quartz.  The pink colour is generally thought to be the result of trace amounts of titanium, iron, or magnesium, however recent studies have suggested that the pink colour is possibly due to microscopic fibres of dumortierite. The origin of this specimen is unknown.
