CRYSTAL QUARTZ - It has a high thermoconductivity, which makes it feel cool to the touch. Some say the origin of the word possibly are the Greek word for ice, as the Greeks believed quartz crystal was fossilized ice (scientists believed this as late as the 16th century).True quartz can be distinguished from glass or lead crystal by its birefringence (double refraction) and the minute air bubbles glass often contains. Quartz is also harder than glass. Quartz passed for diamonds for many centuries.
