It depends on what you mean. Are there quartz crystals on earth that are growing today? Yes. Is that quartz crystal in your rock collection still growing? No. Quartz crystals often form when water with super concentrated silica in it comes into contact with a surface (such as a very small crystal) onto which the silica can precipitate. Crystals also form when magma/lava cools and the different elements in the mixture differentiate into various minerals.
Rose quartz is formed when a small amount of iron is incorporated into a pure quartz (SiO2) matrix. The inclusion of iron (Fe2O3) in many minerals s responsible for the colors that are observed. Iron also turns quartz into Amethyst.

granite is grey in color and has crystals of mica, quartz all embedded in it, giving it a shiny and silver appearance
no it is not accually
Quartz can appear in transparent hexagonal crystals.
Hand specimens of microcrystalline quartz are typically aggregates of crystals rather than single crystals. Microcrystalline quartz is composed of small interlocking crystals that are too small to be individually distinguished without magnification.
The material used to manufacture piezoelectric crystals is quartz. Wrist-watch crystals are often made of quartz. Quartz is a transparent mineral. The statement "There are four quartz in an imperial gallon" is faulty, and logically meaningless.
they are quartz crystals
Yes! Of course! Because they are both crystals.
Piezo electric quartz crystals.
Both a quartz watch and an escalator are examples of periodic movement.
Geodes are often lined with quartz.
They can be used to make glass.
1) The covalent bonds in quartz are much stronger than the ionic bonds in halite. 2) The stronger bonds of quartz make it harder than halite. 3) You can easily scratch halite with a steel knife ,while you cannot scratch quartz.
Quartz
Light entering the crystals is reflected back out - making the quartz sparkle.
