The word “quartz” is derived from the German word “Quarz”, which had the same form in the first half of the 14th century in Middle High German, in East Central German, and which came from the Polish dialect term kwardy, which corresponds to the Czech term tvrdý ("hard").

The Ancient Greeks referred to quartz as κρύσταλλος (krustallos) derived from the Ancient Greek κρύος (kruos) meaning “icy cold”, because some philosophers (including Theophrastus) apparently believed the mineral to be a form of super-cooled ice. Today, the term rock crystal is sometimes used as an alternative name for the purest form of quartz.

HISTORY

There are many different varieties of quartz, several of which are semi-precious gemstones. Clear quartz has an incredibly long history of use in all sorts of fields. It is one of the most famous crystals in the world, and has been significant to cultures on every continent.

COMPOSITION

Quartz is a hard, crystalline mineral composed of silicon and oxygen atoms. The atoms are linked in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2.

HARDNESS

Mohs Scale Hardness: 7

The Mohs scale of mineral hardness is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material.
