Calcium Carbonate
CaCO3

Calcite name is from chalix the Greek word for lime.  This is a most amazing yet, common mineral.  Comprising about 4% by weight of the Earth’s crust and formed in many different geological environments.  Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types.  It forms oolitic, fossiliferous and massive limestones in sedimentary environments.  Calcite serves as the cements for many sandstones and shales.  Limestone becomes marble from the heat and pressure of metamorphic events.  Calcite is even a major component in the igneous rock called Carbonatite and forms the major portion of many hydrothermal veins.

Quartz
SiO2

Quartz has been known and appreciated since pre-historic times. The most ancient name known is recorded by Theophrastus in about 300-325 BCE, is kristallos. The varietal names, rock crystal and bergcrystal, preserve the ancient usage. The root words signifying ice cold and to contract (or solidify) suggest the ancient belief that kritallos was permanently solidified ice.  Quartz is also piezoelectric.

One of the most common minerals found in the Earth’s crust. If pure, quartz forms colourless, transparent and very hard crystals with a glass-like luster. Quartz in its polished form, was the most advanced technology thousands of years ago.  Quartz is also piezoelectric.
