Quartz vibrates when a voltage is applied between opposite faces of a crystal. The frequency of the vibration depends on the thickness of the crystal, and on the direction of the faces compared to the natural planes in the crystal structure.
Amethyst, rose, citrine, smoky, etc., are all examples of quartz. Few minerals come in such an amazing array of colors and crystal habits!
Tanzanite quartz, according to Crystal Age.com, is an artificially created stone that reflects intense energy. Tanzanite aura quartz is made from quartz that has went through a special process. In this process, indium, gold or niobium is used to bind with the quartz and the resulting crystals exhibit a tanzanite appearance.
Quartz singing bowls are made from a complex process where sand is melted and dropped into a centrifugal mold that fuses the particles into a sheet of crystal. This crystal is then fashioned into a bowl shape in the manufacturing process.
The oscillator circuit, which is usually quartz crystal controlled with the quartz crystal in a temperature regulated oven to stabilize its resonant frequency.
A crystal oscillator is a circuit that generates the clock signal that controls the timing of a typical computer. As you may have already guessed, the frequency is mainly controlled by a highly pure crystal of quartz (silicon dioxide).
A quartz clock operates by a piece of quartz crystal. The crystal's wavelength gives off a signal which is read by a digital logic circuit. This signal is then translated into increments of time. The digital data is converted to hours, minutes and seconds.

There are many factories make quartz crystals, from crystal bar to crystal blank. And there are many kinds of products called quartz crystal, such as QCM sensor, people also call it crystal, but it's not a simple crystal but with gold or silver or chrome and other materials plated, with metalized electrode on it.
Amethyst is a variety of crystal quartz.
Pure quartz is a homomogeneous crystal.
Quartz.
There are several differences, the primary one being that on the Mohs hardness scale, diamond is 10, quartz is 8. Quartz crystal is very hard, but diamond is harder.
quartz crystal
the rock that is clear, is well it depends because there is more than 1 clear rock there is the diamond and a few others that you can see through and they are really crystals! it could be quartz..
