Quartz crystal in quartz watches work on the principle?
Piezo-electric Effect
What is the difference between quartz and automatic movements in watches?
Automatic watches are self-winding ie. they need no battery and are wound by the slightest movement of the owner's wrist. Rolex invented the modern automatic back in the 1930s. A quartz watch is powered by a battery - it keeps time by pulsing electrical current through the tiny quartz crystal, which oscillates at a predictable rate and hence keeps very accurate time. Quartz watches can have either an analog dial with the traditional hands or have a digital display - or both.
Who invented quartz?
Walter G. Cady built the first quartz crystal oscillator in 1921. However, the properties of quartz making this possible were first discovered by Jacques and Pierre Curie in 1880.

What does it means a quartz watch?
It is a watch that uses an oscillator based on a quartz crystal to electronically keep time. Older watches used gears and an escape mechanism to govern the speed. In a quartz watch, a precision cut piece of quartz is used in part of a circuit to generate a specific frequency. A quartz clock works similarly, but the quartz oscillator is used to control the speed of a motor.
What is the difference between quartz and diamond?
Quartz is silicon dioxide (sand). Diamond is an allotropic form of carbon.
Can diamond scratch quartz?
There are double-terminated quartz crystals that have remarkable clarity and smooth crystal faces, which have non-scientifically been referred to as diamond quartz--the Herkimer Diamond is one so-named type of quartz crystal.
What is the difference between quartz and crystal?
Both quartz and rock crystal are made up primarily of silicon dioxide. The main difference between them is that rock crystal does not have any significant amount of trace elements that would color it. Quartz does contain coloring trace elements.
Is quartz diamond crystal the same as diamond settings in wedding rings?
Quartz diamond crystal, commonly known as Herkirmer diamond, is not the same as diamond. A Herkimer diamond can be set in a wedding ring.
Is there a difference between milky smoky and rose quartz?
The difference is in varying concentrations of quarts in each crystal.

What is the difference between a quartz and diamond?
There are many differences between quartz and diamond. Primarily, quartz is much softer than diamond. Damond's hardness measurement of 10 -- on the Mohs scale -- is the highest hardness level. Quartz Locations: Brazil, Madagascar, Mozambique; Colors Found: Various; Family: Quartz Hardness: 7.00; Refractive Index: 1.50; Relative Density: 2.60 - 2.70 Diamond Locations: all continents except Europe and Antarctica; Colors Found: Various; Family: Carbon Hardness: 10.00; Refractive Index: 2.41; Relative Density: 3.50 Quartz and diamond have different chemical compositions: diamond is pure carbon, quartz is silicon dioxide.
What are Arkansas' top three minerals?

What is the difference in silicates such as asbestos mica and quartz?
The difference is in their chemical composition and crystal structure which gives them different properties.
