TitleCinnabar with hemimorphite, calcite and malachite
DescriptionCinnabar, HgS (mercury sulfide), is an important mercury ore mineral. It often shows a distinctive violet to red color. In this sample it is seen with brown hemimorphite, Zn4Si2O7(OH)2•H2O (hydrated zinc silicate hydroxide). White to clear calcite, CaCO3 (calcium carbonate), and greenish gray malachite, Cu2(CO3)(OH)2 (copper carbonate hydroxide), are also present but are hard to see. The specimen is 6 cm across.
