History & Lore:
There is not 100% agreement regarding the exact origins of the name Quartz, but the two most widely accepted opinions are that the word Quartz is derived from the Greek 'krystallos', meaning “ice”, or the German 'quarz'.

Some of the earliest primitive tools fashioned by man some 2.5 million years ago, and discovered in the Omo valley in Ethiopia were made of Quartz. It is believed that Quartz was used because of its hardness and isotropic brittleness that made the fashioning of the tools relatively easy.

Chipped flint projectile points used for fire-making have been found on Mousterian sites in western Europe that date back around 40,000 years.

In addition to its use in tool-making, certain varieties of Quartz were used for divination. Spherical Quartz rock crystals were often shaped into crystal balls and used for disease diagnosis and awareness of events occurring in distant places.

More recently there was major production of synthetic Quartz during World War II. This synthetic Quartz was used to supply crystals for radios.

Because of its piezoelectric and pyroelectric properties, Quartz is commonly used in the production of watches, clocks, computers, and radios.

Grey Quartz is believed to help stabilize energies and develop serenity. In addition to this, it is believed to bring inspiration to the wearer and strengthen creativity.
