White Quartz is one of the most important minerals on earth and makes up one of the
most popular gemstone groups in the world of colored stones. It is the second most
abundant mineral found in Earth's continental crust, second only to the feldspars. The
name 'quartz' is thought to be derived from the German word 'quartz', which likely
originated from the Slavic and Polish words meaning 'hard'. The name is descriptive in
regard to quartz being the definitive mineral that measures 7 on the Mohs scale of
hardness.
