Quartz typically forms last in Bowen's reaction series due to its high resistance to weathering and its stability under low-temperature conditions. As magma cools and crystallizes, quartz is one of the minerals that will precipitate out towards the end of the crystallization process.
Tourmaline often occurs in long thin needles densely included inside Quartz. Such material is known as Tourmalinated Quartz. Tourmalinated quartz is carved into valuable ornamental objects and figures.
Quartz is everywhere. Every white grain of sand is quartz.
The subgroup for quartz is silicates.
Amethyst is a violet form of quartz.
watch batteries last for 1-2 years, check the manual
Smoky quartz is normally found in granite mountains. Smoky quartz is regular quartz which is exposed to radiation on a long term basis.
In solidifying igneous rock, usually quartz.

A small quartz crystal can grow about 1mm a week assuming it is in a stable matrix.
"Shapeless" quartz is usually associated with tectonic movements and metamorphic rocks. In granites it is about the last mineral to crystallise and it fills the spaces between the micas and feldspars. In a crystalline form it forms long hexagonal (six sided) usually clear transparent crystals which are topped off with a hexagonal pyramid
Great question: A piezoelectric material such as quartz might a very long time, but they do age. But for applications where absolute frequency stability is needed, other methods are used. See: http://en.wikipedia.org/wiki/Crystal_oscillator
The lifespan of a quartz watch movement can vary depending on the quality of the movement and how well it is maintained. Generally speaking, a quartz movement can last anywhere from 10 to 20 years before it may need servicing or repairs. Regular maintenance and care can help prolong the lifespan of a quartz watch movement.
it was formed from extreme pressure for a long time under the earth.
It is made out of sand which is silicone dioxide also called quartz.
The plural of quartz is quartz or quartzes.
