Rose quartz (SiO₂), illustrating vitreous lustre. The colour comes from impurities in the quartz. Iron, manganese, or titanium can cause this colour. Specimen source: USask teaching collection.

Manganese oxide powdered quartz crystals from a vug at the Mesquite Gold Mine in southeastern California
Main parts of my small collection of stones, picked on the Pacific beaches, not including fossils, jasper and various unidentified stones.
Other name for it is Scolecite
Locality: Fat Jack Mine, ane Mountain, Crown King, Pine Grove District, Bradshaw Mts (Bradshaw Range), Yavapai Co., Arizona, USA
Size: Crystal is 1.4 inches tall.
Subject: Rock, quartz
If you see any visions from gazing into this crystal I am not liable for any direct, indirect, or incidental, consequential, real, imagined or punitive damages arising from entering a trance. Here is the link to the original size: farm3.static.flickr.com/2657/4180306484_37c5d71ac7_o.jpg
Canon 100mm macro lens, 1/60 sec, f/4.5, ISO 100 Single 100W incandescent light left of quartz crystal. Manual Focus with focal plane inside of crystal. Used Lightroom to saturate and bring out the hues of the light reflecting of inside of the grain structure of the crystal lattice.

PS - the smallest of those is 6 inches long, absolutely amazing!
Small but ultra-clear crystals. Very hard to photograph because they are so clear. About 3-4mm long. Waitawheta River, Karangahake Gorge.
Twinned quartz from Madagascar.
A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 5100 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
The silicates are the most abundant and chemically complex group of minerals. All silicates have silica as the basis for their chemistry. "Silica" refers to SiO2 chemistry. The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4. Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens "belong" to each silicon. The resulting formula for silica is thus SiO2, not SiO4.
The simplest & most abundant silicate mineral in the Earth's crust is quartz (SiO2). All other silicates have silica + impurities. Many silicates have a significant percentage of aluminum (the aluminosilicates).
Quartz (silicon dioxide/silica - SiO2) is the most common mineral in the Earth's crust. It is composed of the two most abundant elements in the crust - oxygen and silicon. It has a glassy, nonmetallic luster, is commonly clearish to whitish to grayish in color, has a white streak, is quite hard (H≡7), forms hexagonal crystals, has no cleavage, and has conchoidal fracture. Quartz can be any color: clear, white, gray, black, brown, pink, red, purple, blue, green, orange, etc.
The specimen shown above is Japan-law twinned quartz of hydrothermal origin, derived from a breccia body.
Locality: unrecorded/undisclosed site north of the town of Andilamena, northern Toamasina Province, northeastern Madagascar

Photo gallery of quartz:
(Pra129) Prasiolite Quartz (Brazil). 7.89ct, 12.15x12.17x9.31mm. Custom Barion Square.
I purchased this from a Brazilian dealer in Tucson. I paid a small premium for this color -- described as "super extra" at the dealer's booth. It is a little nicer than the normal prasiolite in that it lacks much of the gray mask most of these stones have.
I'm pretty pleased with this design too -- I think I'll use it again in some other materials.
Arsenopyrite with Quartz. The mineral is iron arsenic sulfide. Siglo XX Mine. Llallagua, Bustillos Province, Potosi Department, Bolivia. (Collection of the Mines Museum of Earth Science. Golden, Colo.)
Another necklace featuring Fiona Sands' delicious boro beads, this time a hot pink set, with flashes of purple and orange. I have combined them with highly refective mystic quartz nuggets, clusters of wrapped pink sapphire, amethyst, garnet and carnelian, and some Hill Tribe silver.

"Dendritic agate" is a rockhound term applied to fine-grained quartz / chalcedony having dark-colored, irregularly-shaped to branching inclusions of one or more opaque minerals.
Locality: unrecorded / undisclosed
Every PAL colour TV has one of these 64-microsecond delay lines. Video recorders have them, too. They compensate for phase errors in the colour subcarrier and prevent the display of false colours.
Quartz Peak cirque in the Niut Range seen from the north slopes of Peak 9560. Our basecamp was at the bottom of the photo. This thing was mapped as a glacier but it's all moraine now! :o

The quartz seen here is a broken specimen - no obvious crystal faces are present.
