Quartz

in most documentation the length comes 1st but it usually doesn't matter unless you are doing something other than adding or multiplying.

mineral

Galena is a common mineral that contains lead and is often found alongside silver ores such as argentite. These minerals are typically found in hydrothermal veins and are important sources of lead and silver production.

A clear quartz rock by itself actually isn't worth very much simply because it can't be used for many different things. You can often find little pieces of quartz rock in a store for around one to five dollars. However, if you are purchasing quartz for countertops in your home then it's a very different story. Quartz countertops prices can range anywhere from $100 to $120 a square foot - the difference is that it is shaped and in a useable form where as a rock cannot be used for much.

It's just like if a car didn't run it wouldn't be worth very much, but if you got it running the value increases substantially.

Quartz can be transparent (clear) or translucent (you can see light through it, but shapes are very fuzzy).

Anything under the 7 of the Moh's Hardness Scale, which is the number assigned to quartz. Minerals that can scratch quartz include topaz, corundum and diamond - pretty much everything else won't scratch it.

This would depend upon a number of factors. Massive, or crystalline? Colorless, or colorful? Clear or opaque? Fractured or flawless? From the Swiss Alps, or from Arkansas? A buck a pound will get you good tumbling grade agate, but a well crystallized rose quartz specimen, or top grade rutilated quartz, or a nice Swiss smoky quartz crystal crowned with pink fluorite crystals... you can add two to four zeroes.

Quartz is a naturally occurring silicate mineral composed of silicon dioxide (SiO2). Its hardness is 7 on the Mohs scale and it is in the trigonal crystal system. Quartz possesses a glassy luster and does not exhibit cleavage. The average specific gravity of quartz is 2.62. Quartz can be found in all three rock types, igneous, metamorphic, and sedimentary. Quartz has a white streak, but specimens can be appear colored by impurities or exposure to heat or radiation to hues of white, pink, red, orange, yellow, blue, green, black, smokey, milky, or purple.
Quartz is a mineral, chemical composition of silicon dioxide, one of the most common minerals on the planet.

Sonata is a particular brand of the Titan company. Quartz describes a type of movement used in the watch design. Titan does use quartz technology in their watches.

Heat capacity is a function of temperature so there is no single value that is valid at all temperatures. That said, The heat capacity ranges from about 680 to about 730 J/kg·K. If you just estimate it as 700 J/kg·K you won't be far off.

• cut quartz crystals are used in electronics oscillators to maintain a precise and constant frequency
• a quartz crystal struck by a small spring loaded hammer is used to generate a short high voltage to create a spark that ignites gas in propane grills, butane lighters, etc.
• quartz of various colors is used as semiprecious gems in jewelry
• slices of transparent quartz are used to make windows that pass UV light (ordinary glass blocks UV light)
• quartz was an important raw material for making stone tools during the Stone Age
• since World War 2 much of the quartz needed by technological industries is synthetic and of higher quality than is usually available naturally from quartz mines
• etc.

The most significant difference between a Swiss and a Japanese replica watch is the movement, while Swiss replicas come with an ETA movement the Japanese replicas come with a Miyota movement, similar to the movement found on Citizen and Seiko watches.

Swiss replica watches's price usually range from $400 to $600

Mens Japanese watches's price range between $180 to $300 depending on the functions they have. Ladies Japanese watches usually sell for $100 to $200.
