| ABOUT THIS GEM: | Quartz |
Quartz is a family of minerals with the same chemical composition (silicon dioxide) and similar physical properties. Some say the origin of the word quartz is the Saxon word querkluftertz, meaning "a cross vein ore," which later was condensed to querertz.
However, it also might have been named after the Slavic word kwardy, or "hard," or possibly the Greek word for ice, as the Greeks believed quartz crystal was fossilized ice (scientists believed this as late as the 16th century). Quartz's high thermoconductivity, which makes it feel cool to the touch, may have added to this belief. The two varieties of quartz are macrocrystalline (crystals recognizable with the naked eye) and microcrystalline or cryptocrystalline (crystals too small to see without high magnification).
