Enhydro Hyaline Quartz or Rock Crystal Quartz with Fluid Inclusions 14.3 gr - mm 35 x 19 x 15 Raw Minerals Crystals Stones Rocks for Collection or Crystaltherapy, one Drop of Water included within, only a piece, as in photo.
Silicon Dioxide (SiO2).
P.S. a small black mark, easily removable with alcohol or soap, indicates the area where the drop of water is visible, which can be seen moving by tilting the crystal.


During the quartz crystal growth may have included extraneous material visible in transparency if the crystals are clear. Inclusions, both solid and fluid trapped, surviving intact to us, give us without the destruction of the crystal, a lot of information about temperature, pressure and composition of fluid in the slot and participants in the process of crystallization.

Hyaline Quartz, also commonly called Rock Crystal, is a completely colorless variety of quartz. It is usually perfectly transparent, with an appearance similar to glass and artificial crystal, from which it can be easily distinguished, like all mineral substances, due to the cold sensation it causes to the sage with the tongue.
Hyaline quartz, which comes from all over the world, contains an enormous variety of inclusions. Unlike milky quartz, rich in various elements or inclusions, they are completely transparent.

Quartz (silicon dioxide, SiO2, is the second most abundant mineral in the earth's crust (about 12% of its volume) after feldspars.
The etymology of the name is not certain, but for the ancient Greeks quartz was defined as crystal (from the Greek κρύσταλλος, krýstallos, ice). In fact, they considered this mineral a variety of ice cold to the point that it could no longer be dissolved.
Quartz has a crystalline structure made up of silicon and oxygen tetrahedrons joined together by the 4 vertices to form spirals. The habitus (the shape) is a hexagonal prism with the faces of two rhombohedrons at the vertices arranged in such a way as to form a hexagonal bipyramid. Quartz can have an elongated prismatic shape.
Quartz is a common constituent of acidic intrusive magmatic rocks, among which the best known is granite; it is also abundant as a component of sedimentary rocks, preferably in sandstones due to its high resistance to chemical degradation by atmospheric agents and its insolubility in water and in metamorphic rocks.
Being one of the most common minerals of the earth's crust, quartz has a large number of different varieties, with macroscopic crystals visible to the naked eye, or crystals so small as to be visible only under a microscope or even invisible with such an instrument. Although many of the variety names have historically come from the colors of the mineral, current scientific naming schemes refer primarily to the microstructure of the mineral. Usually, but not always, color is a secondary identifier.
In addition to hyaline quartz, perfectly colorless and clear, there are numerous other varieties of quartz, many of which are for sale on our site:
Chalcedony, Agate, Moss Agate, Chrysoprase, Onyx, Carnelian, Sardonyx, Jasper, Heliotrope, Aventurine, Tiger's Eye, Cat's Eye, Bull's Eye, Hawk's Eye, Amethyst, Ametrine, Citrine or Madeira, Rose Quartz, Quartz blue, Prasiolite, Milky Quartz, Smoky Quartz, Morion, Rutilated Quartz, Tourmaline Quartz, Dendritic Quartz, etc.
Quartz is a material with remarkable chemical stability and is resistant to acids except hydrofluoric acid. It has high hardness (7 on the Mohs scale), mechanical and heat resistance. The quartz has no cleavage. Some physical properties of quartz crystals are piezoelectricity and pyroelectricity, i.e. the ability to electrically polarize the opposite faces of the crystal following the mechanical deformation caused by compression or after heating. From an optical point of view, quartz has high transmissibility in the visible and especially in the ultraviolet.
