Why are mineral crystals in obsidian too small to see without a microscope?
The rock cools so rapidly from magma that crystals barely have time to form.
What is the general name for microcrystalline quartz in sedimentary rocks?
Chalcedony
How much are most quartz crystals worth?
Most Quartz Crystals are worth as much as a grain of sand. Most sand is composed of minute crystals of Quartz. The make-up of Quartz is found in the Chemical formula of Silica or (silicon dioxide, SiO2). Pure quartz is colorless or white; colored varieties include rose quartz, amethyst, smoky quartz, milky quartz, and others. Quartz goes by an array of different names. The most important distinction between types of quartz is that of macrocrystalline (individual crystals visible to the unaided eye) and the microcrystalline or cryptocrystalline varieties (aggregates of crystals visible only under high magnification). Chalcedony is a generic term for cryptocrystalline quartz. The cryptocrystalline varieties are either translucent or mostly opaque, while the transparent varieties tend to be macrocrystalline. Although many of the varietal names historically arose from the color of the mineral, current scientific naming schemes refer primarily to the microstructure of the mineral. Color is a secondary identifier for the cryptocrystalline minerals, although it is a primary identifier for the macrocrystalline varieties. This does not always hold true. So in truth, Quartz is one of the most plentiful substances on Earth!

Are rock crystals the same as quartz?
Yes! Of course! Because they are both crystals.
What are the five varieties of quartz crystals?
There are many varieties of quartz crystals that can be considered classifications beyond just five. Some of the names for the varieties are Macrocrystalline, Microcrystalline and Cryptocrystalline.

Microcrystalline quartz formed by recrystallization of silicaeous oozes in seafloor sediments?
Chert.
Flint chert and jasper are microcrystalline forms of what?
Flint, chert and jasper are all forms of the mineral quartz, which are generally formed in sedimentary rock.

Is rose quartz rare?
No. It is very common and easy to find.
How do you use quartz in a sentence?
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.
Are quartz crystals organic?
No. They are inorganic.
What is a twin scepters?
they are quartz crystals
What crystals are used in timepieces and electronics?
Piezo electric quartz crystals.
