How is milky quartz formed?
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.
Are hand specimens of microcrystalline quartz single crystals or aggregates of crystals?
Specimens of microcrystalline quartz are aggregates of microscopic crystals
Where to sell your crystals?
where to sell my quartz crystals
Are rock crystals the same as quartz?
Yes! Of course! Because they are both crystals.
What crystals are only visible with magnification?
quartz
what does a rock crystal look like?
The image shows a cluster of purple quartz crystals.
How are quartz crystal formed?
Quartz crystals typically grow hydrothermally, in hot, pressurized, silical solutions.

What type of rock is formed by interlocking crystals?
hard strong rocks
What Does Purple Look Like?
Purple is a light burgundy (dark red) with a hint of blue.
Are hand specimens of microcrystalline quartz single crystals or aggregates of crystals?
Specimens of microcrystalline quartz are aggregates of microscopic crystals

Could a mineral have a crystal form but no cleavage?
Yes. Quartz can have very well-formed crystals but lacks cleavage.
What is sugar quartz?
Sugar Quartz is a gemstone with a natural surface texture much like fine sugar crystals formed by natural phenomena of micro-crystalline facets.
How is amethyst formed by nature?
Amethyst crystals are actually quartz (SiO2) crystals with a purplish hue derived from impurities of iron and aluminum. The crystalline structure forms from the latticework arrangement of silicon and oxygen atoms unique to quartz. Quartz crystals like amethyst can develop from silica saturated solutions or even from molten silica solutions.
Why is there no quartz formed in magma after it has cooled?
If you can't see its crystals without a microscope it's because the rock solidified too rapidly for visible crystals to form. Whether or not quartz is found in cooled magma/lava is basically a product of the chemical makeup of the molten rock. Quartz is the predominate silicate mineral in felsic igneous rocks, but may be non-existent in mafic igneous rocks. If you are referring to the fact that most felsic igneous rocks containing quartz do not exhibit well formed quartz crystals, it is because quartz is one of the last minerals to crystallize from magma, and solidifies in the voids between other minerals that have already crystallized.
What is rose quartz made out of?
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.
