Sphalerite is a mineral that is the chief ore of Zinc. It consists
mainly of Zinc Sulfide in crystalline form but almost always contains valuable
Iron. When the Iron content is high, it is an opaque black variety called
Marmatite. It is usually found in association with Galena, Pyrite, Calcite,
Dolomite and Fluorite. It is usually yellow, brown or gray to gray-black
in color and may have a shiny or dull luster or sheen.

Copper is a reddish colored metal with a high electrical and thermal
conductivity. It has its characteristic color because it reflects red
and orange light and absorbs other frequencies in the visible spectrum due
to its band structure. It is in the same family as Silver and Gold and
is a malleable metal. It is beautiful natural or polished.

Aqua Aura is a metallic light blue tint on Clear Quartz from an
electrical infusion of gold powder. They are created by a special process
treating the natural Quartz crystals with vaporized, finely powdered pure
gold. This results in a stunning iridescent rainbow flash on the brilliant
blue crystals. Aqua Aura is said to have many positive effects in the
metaphysical world.

Fluorite, also referred to as fluor-spar, is a mineral composed of Calcium
Fluoride. It is a widely occurring mineral found world wide and is often
found with metallic minerals such as Galena, Sphalerite, Barite, Quartz
and Calcite. Fluorite may fluoresce strongly in ultraviolet light
which may be due to the presence of some impurities such as Yttrium.
Blue is the most common color but red, purple, green, yellow and white are
also frequent. It can be used in high performance telescopes, camera
lens, enamels and in the making of opalescent glass. |

Bismuth is a native element but native crystals are extremely rare.
Peru is one of the world's major sources. These crystals are grown in
laboratories in the United States. Bismuth is scarce as Silver, heavier
than Lead and is classified as a semi-precious semi-metal. It is non-toxic
to humans. It is used in medicine and cosmetics, applications in inks,
paints, free-machining steels and fire sprinklers.

Crystals of Sulfur are usually yellow to yellowish-brown blocky dipyramids.
Also it is found more typically as powdery yellow coatings. Native Sulphur
is usually formed from volcanic action - as a sublimate from volcanic gasses
associated with Realgar, cinnabar and other minerals. It is found in
some vein deposits as an alteration product of sulfide minerals.

Pyrite, or Iron Pyrite, is an Iron sulfide with isometric Crystals that usually
appear as cubes. It is brittle and can break or powder easily.
Its metallic luster and brass yellow hue have earned it the nickname of "fool's
gold" due to many miners mistaken it for the real thing. Ironically,
small quantities of actual gold are sometimes found in Pyrite. It is
the most common of the sulfide minerals and is usually found with other sulfides
or oxides in Quartz veins, sedimentary or metamorphic rocks.

Gibbsite is one of the mineral forms of aluminum hydroxide and also
sometimes called hydrargillite. Gibbsite is an important ore of Aluminum
in that it is one of three main phases that make up the rock Bauxite. Gibbsite
is a secondary mineral mainly of tropical and subtropical occurence.
Named by John Torrey in 1822 in honor of Colonel George Gibbs, a wealthy
import merchant who was a geologist and mineralogist. Notable
occurrences include Brazil, Central Africa, Germany, Hungary, France,
Guyana and USA (mainly Alaska).

consisting chiefly of the silicates of iron, zirconium, and lime. Some
samples of Eudialyte have been found to have up to 46 different elements.
The zirconium has many uses from the production of synthetic fibers, in
construction materials for aircraft and space vehicles and in the
manufacture of super-hard alloys. Eudialyte is found in Arkansas,
Greenland, Russia, Norway, Canada and Madagascar.

Broshite is a phosphate mineral with the chemical formula CaHPO₄·2H₂O.
It forms colorless to pale yellow monoclinic prismatic crystals and as
powdery or earthy masses. It is the phosphate analogue of the arsenate
pharmacolite and the sulfate gypsum. Broshite was first described in
1865 for an occurrence on Aves Island, Nueva Esparta, Venezuela, and named
for the American mineralogist George Jarvis Brush (1831–1912). It is
believed to be a precursor of apatite and is found in guano-rich caves,
formed by the interaction of guano with calcite and clay at a low pH. It
occurs in phosphorite deposits and forms encrustations on old bones. It
may result from runoff of fields which have received heavy fertilizer
applications. Associated minerals include tanarakite, ardealite,
hydroxylapatite, variscite and gypsum. Brushite is the original
precipitating material in calcium phosphate kidney stones. It is also one
of the minerals present in dental calculi.

ingredients and cooling rapidly. Libyan desert glass or great sand sea
glass is a substance found in areas in the Libyan Desert. Fragments of
desert glass can be found over large areas, up to tens of kilometers. The
Libyan desert glass has been dated as having formed about 26 million years
ago. It was knapped and used to make tools during the Pleistocene. Today's
glass is used to make windows, drinking containers and many other
articles.

Barite or Baryte is a mineral consisting of Barium sulfate and is
generally white or colorless. The baryte group consists of baryte,
celestine, anglesite and anhydrite. Baryte commonly occurs in lead-zinc
veins in limestones, in hot spring deposits, and with hematite ore. It is
used in the manufacture of paints and paper. Although Barite contains a
'heavy' metal, Barium, it is not considered to be a toxic chemical because
of its extreme insolubility.

Quartz is the second most common mineral in the Earth's continental
crust. It is mainly composed of Silica or Silica based minerals.
Although Quartz is known by a variety of names, the most important distinction
between types of Quartz is that of macro-crystalline, individual crystals
visible to the unaided eye, and micro-crystalline, where aggregates of crystals
are only visible under high magnification. There are many forms of Quartz
including Chalcedony, Amethyst, Citrine, and Carnelian which are results of
mineral impurities or heat treatments.
Rutile is a mineral composed primarily of Titanium Dioxide. Rutile
has among the highest refractive indices of any known mineral and also
exhibits high dispersion. Rutile is known to contain up to 10% Iron as
well as significant amounts of Niobium and Tantalum. Rutile creates small
needles within crystals that can be seen when held up to light.
