History &Lore:
Quartz
is the second most abundant mineral in the Earth's continental crust, after feldspar.
There are many different varieties of quartz, several of which are semi-precious gemstones. Especially in Europe and the Middle East, varieties of quartz have been used, since antiquity. It is one of the most
commonly used minerals in the making of jewelry and hardstone carvings.
Usually called rock crystal, pure quartz (sometimes called clear quartz), is colorless and transparent (clear) or translucent, and has often been used for hardstone carvings, such as the Lothair Crystal. Common colored varieties include citrine, rose quartz, amethyst, smoky quartz, milky quartz, mint quartzand others.
The word "quartz" comes from the German Quarz in which is of Slavic origin (Czech miners called it křemen). Other sources attribute the word's origin to the Saxon word Querkluftertz, meaning cross-vein ore.
Quartz is the most common material identified as the mystical substance maban in Australian Aboriginal mythology. It is found regularly in passage tomb cemeteries in Europe in a burial context, such as Newgrange or Carrowmore in Ireland. The Irish word for quartz is grian cloch, which means 'stone of the sun'. Quartz was also used in Prehistoric Ireland, as well as many other countries, for stone tools; both vein quartz and rock crystal were knapped as part of the lithic technology of the prehistoric
peoples.
In the 17th century, Nicolas Steno discovered that regardless of a quartz crystal's size or shape, its long prism faces always joined at a perfect 60° angle.
