Quartz is a mineral. No other minerals contain quartz.
Ultrapure quartz is one material that passes both the 254nm and 185nm frequencies of UV light developed by a mercury plasma tube, which itself is constructed using ultrapure quartz. If the quartz is not very pure, not much of the 184 nm frequency will get through. I think there are certain Teflons that will also pass UV light.
Quartz comes in every color imaginable, but the most popular purple gemstone bead I think would be amethyst. Some quartz is even dyed. the most common quartz colors I have seen are clear, white, rose, yellow, and smoky. the smoky and rose quartz being my favorite. If you have purple gemstone beads and don't know what it is, it could be quartz but most likely amethyst
I found a dazzling piece of quartz in the yard.
Some are, some aren't.
Some scientists think we are made of quartz because of its abundance in nature.
Pure quartz is colorless. Trace amounts of transition metal impurities in the quartz are what give it its color.
Milky quartz is caused when fluids are trapped in the crystal early in its formation. Milky quarts is considered a flaw of the quartz by some.
Depends on the quality of jade and where it is from. Some jade is dyed to make the color brighter and the stone is not of good quality.
