Quartz rock will give you the most accurate time and date. It is commonly used in watch production.
Most of the wrist watches operate on quartz mechanism. It is necessary to understand the mechanism in a car to perform minor repairs.
Pure quartz is colorless. Trace amounts of transition metal impurities in the quartz are what give it its color.
This site will give you excellent information, here is an excerpt and the site:Enter the Quartz Clock. Quartz timepieces use the nature of the quartz crystal to provide a very accurate resonator which gives a constant electronic signal for timekeeping purposes. Quartz crystals are piezoelectric, which means that they generate an electrical charge when mechanical pressure is applied to them. They also vibrate if an electrical charge is applied to them. The frequency of this vibration is a function of the cut and shape of the crystal. Quartz crystals can be cut at a consistent size and shape to vibrate at thousands of times per second, making them extremely stable resonators for keeping very accurate time.* http://www.physlink.com/Education/AskExperts/ae559.cfm
how about u give me the answer
Yes, amethyst is a type of quartz that contains traces of iron impurities that give it its purple color.
because it is time to give it up!
Quartz itself is transparent or transluscent. But trapped impurities such as iron, copper, etc give quartz a full rainbow of colors to choose from.
it is in the urinary systemJust below the kidneys. Not too sure if this is as accurate as you want it. But this is the best i can give you. Hope this helps!
"Rose quartz is a type of quartz which exhibits a pale pink to rose red hue." -Wikipedia Well, I suppose it's made of quartz, then, isn't it? 'Cause the name Rose QUARTZ doesn't give that away.
Apatite quartz refers to a type of quartz crystal that contains inclusions of apatite minerals. These inclusions give the quartz a distinctive look and can vary in color from green to blue to yellow. Apatite quartz is highly valued by collectors for its unique beauty and metaphysical properties.
You can sell watches to many pawn shops. -They don't give good value for them.
