Of all the minerals found on Earth, quartz is the most common. It occurs in almost every type of rock. It comes in five common yet different crystallized forms and
many more noncrystalline forms. It is valuable in industry and communications. And it accepts other minerals, which give it colors and patterns that far exceed the beauty of any other mineral.
Quartz has long been the cornerstone of the gem and lapidary industry and the collecting hobby. We would be hard-pressed (even in 2020) to find many people who don’t have some variety of it in their collections.
This mineral has a relatively simple chemical structure. It is made of an atom of silicon (one of Earth’s most common elements) and two of oxygen (its most common element). Together, they form molecules that take the shape of a tetrahedron, rather like a pyramid with one corner pulled out to distort the whole. These, in turn, attach in a spiral fashion, forming beautiful hexagonal crystals that usually have pyramidal, or pointed, terminations.
