Quartz is the second-most-abundant mineral in Earth's continental crust, after feldspar. Its crystal structure is a continuous framework of SiO4silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2.
There are many different varieties of quartz, several of which are semi-precious gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Europe and the Middle East.
Etymology
The word "quartz" is derived from the German word "Quarz" and its Middle High German ancestor "twarc", which probably originated in Slavic, cf. Czech tvrdý ("hard"), Polish twardy ("hard"), Serbian and Croatian tvrd ("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 supercooled ice. Today, the term rock crystal is sometimes used as an alternative name for the purest form of quartz.
In Apple computer's OS X operating system, Quartz is the Quartz 2D and Quartz Compositor part of the Core Graphics framework. Quartz includes both a 2D renderer in Core Graphics and the composition engine that sends instructions to the graphics card. Because of this vertical nature, Quartz is often synonymous with Core Graphics.
In a general sense, Quartz or Quartz technologies can refer to almost every part of the Mac OS X graphics model from the rendering layer down to the compositor including Core Image and Core Video. Other Apple graphics technologies that use the "Quartz" prefix include:
Quartz 2D & Quartz Compositor
Quartz 2D is the primary two-dimensional (2D) text and graphics rendering library: It directly supports Aqua by displaying two-dimensional graphics to create the user interface, including on-the-fly rendering and anti-aliasing. Quartz can render text with sub-pixel precision; graphics are limited to more traditional anti-aliasing, which is the default mode of operation but can be turned off. In Mac OS X v10.4, Apple introduced Quartz 2D Extreme, which allows Quartz 2D to use supported GPUs for rendering. In Mac OS X 10.4, Quartz 2D Extreme is not enabled by default, because it may lead to video redraw issues or kernel panics. As of Mac OS X v10.5 Quartz 2D Extreme has been renamed to QuartzGL. However, it still remains disabled by default, as there are some situations where it can degrade performance, or experience visual glitches; it is a per-application setting which can be turned on if the developer wishes.
A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency. This frequency is commonly used to keep track of time, as in quartz wristwatches, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers. The most common type of piezoelectric resonator used is the quartz crystal, so oscillator circuits incorporating them became known as crystal oscillators, but other piezoelectric materials including polycrystalline ceramics are used in similar circuits.
Quartz crystals are manufactured for frequencies from a few tens of kilohertz to hundreds of megahertz. More than two billion crystals are manufactured annually. Most are used for consumer devices such as wristwatches, clocks, radios, computers, and cellphones. Quartz crystals are also found inside test and measurement equipment, such as counters, signal generators, and oscilloscopes.

Quartz
by: MarillionI can imagine nothing more tedious
Than trying to have fun with you again
Maybe it's just something in my mind
But I hate feeling like I'm trying all the time
It's a kind of lie when we pretend that we're still friends
I'm sure you're not exactly short of people to
Hang out and laugh at your jokes
Tell you you look great, you wouldn't want me around
Making it all feel forced"and put down
And every time I smile to wonder if I'm laughin' at you
And with every little grin you don't want to be wonderin'
Just exactly what it is I'm taking pleasure in
Although I always said
We were basically the same and all one
All one, it's so easy to persuade myself
I'm clockwork and you're quartz
I guess that irony
Will surely be
The death of me
And every time I smile do you wonder if I'm laughin' at you?
And with every little grin you don't want to be wonderin'
Although I always said
We were basically the same and all one
All one, it's so easy to persuade myself
I'm clockwork and you're quartz
You're only happy when you're oiled and jeweled
You're only happy when you wind me up and I know
You're so reliable it isn't true
And it's so easy for me to break down?
If I could jump a ride between the skin and silicon then
We could join hands and understand, Hallelujah
But I listen to the ticking, I guess we're worlds apart
It's so hard, so hard
I know there's no going back
And you know there's no going back
You're only happy when you're oiled and jeweled
You're only happy when you're oiled and jeweled
You're never happy
I need maintenance, I need patience
I'm not foolproof, I'm not waterproof
I'm not shockproof, bombproof, bulletproof
Fireproof, leak-proof, childproof, stain-proof, pressure-proof
I know I told myself
We're all basically the same and all one all one
You know, sometimes I just can't help myself
I'm clockwork and you're quartz
I'm clockwork and you're quartz
I know I never get the balance right
And turn up half an hour late night after night
And being totally dependable is so very commendable
Although you're never wrong
