Chalcedony is a cryptocrystalline form of silica, composed of very fine
intergrowths of the minerals quartz and moganite. Chalcedony has a waxy
luster, and may be semitransparent or translucent. It can assume a wide
range of colors, but those most commonly seen are white to gray,
grayish-blue or a shade of brown ranging from pale to nearly black.
Okenite is a silicate mineral that is usually associated with
zeolites. It most commonly is found as small white "cotton ball"
formations within basalt geodes. These formations are clusters of
straight, radiating, fibrous crystals that are both bendable and fragile.
Because of this common shape, Okenite is often called a "warm and fuzzy"
stone because it brings feelings of the "warm fuzzies", feelings of
comfort and belonging. It was first discribed in 1828 for an occurrence at
Disko Island, Greenland and named for German naturalist Lorenz Oken.

Hematite is a mineral form of Iron oxide. It is a very common material
that has a black to steel to silver-grey color and may also appear reddish
brown. Hematite is a heavy metal and when it is polished it is consider to
many to be of gemstone quality. It is very popular in jewelry and Native
American art.
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.

Aragonite is a Carbonate mineral that can occur in conjunction with
Calcium Carbonates. Aragonite differs from Calcite in the formation
of the Crystal shapes which can be in lattice, crystal, columnar or fibrous
in many different designs, shapes and sizes. Aragonite will form in
mollusk shells, oceans and salt water caves as inorganic precipitates called
marine cements and speleotherms. Ammolite is a form of Aragonite with
impurities that make it iridescent and valuable as a gemstone.

The Tourmaline mineral group is chemically one of the most
complicated groups of Silicate minerals. Its composition varies widely
with Sodium, Calcium, Iron, Magnesium, Lithium, Aluminum, Boron and other
elements. It has a wide variety of colors including black, blue-black,
brown, yellow, red, green, pink and is rarely colorless. This mineral is
found in igneous rocks, like Granite Pegmatite, and metamorphic rocks such
as Schist and Marble.

Geodes are geological rock formations which occur in sedimentary and
certain volcanic rocks. They are essentially rock cavities or vugs with
internal Crystal formations or concentric banding. The exterior is generally
Limestone while the interior contains Quartz Crystals and/or Chalcedony deposits.
If the Geode is completely filled with Crystal, being solid all the way through,
it is then called a nodule.

Labradorite is a Feldspar mineral that occurs in large Crystal masses
in anorthosite and shows an iridescence or "play of colors." Gemstone
varieties of Labradorite exhibiting a high degree of iridescence are Spectrolite,
Moonstone and Sunstone. High quality samples with good iridescent qualities
are desired for jewelry.

Malachite is a Copper Carbonate mineral that often forms botryoidal,
fibrous or stalagmitic masses. It is often the result of the weathering
of Copper Ores and is commonly found with Azurite, Goethite and Calcite.
It is typically associated with Copper deposits including Limestone which
is the source of the Carbonate. Malachite is found in many regions world
wide and is usually shaded green in color.

Calcite is a Carbonate mineral that is most widely distributed on the
Earth's surface. It is a common constituent of sedimentary rocks with
Limestone in particular. A Calcite formation can take on many different
shapes and sizes which is dependent on the location, ground water occurrence
and temperature. Calcite is usually white or colorless but can be gray,
red, yellow, green, blue, violet, brown or black. The deeper the color
is usually indicative of the definitive impurities from the earth or water.
Limonite is an ore consisting of a mixture of hydrated Iron
Oxide-Hydroxide of varying composition of minerals such as Goethite,
Lepidocrocite, or Jarosite. It has been mined with Hematite as an Ore for
the production of Iron. Limonite is heavy and has a yellow-brown color. It
is often used as the pigment ochre in many paints. Gossan is
intensely oxidized, weathered or decomposed rock, usually the upper and
exposed part of an ore deposit or mineral vein. In the classic gossan or
iron cap all that remains is iron oxides and quartz, often in the form of
boxworks. Rosasite is an uncommon mineral belonging to the
Carbonate group of minerals. It has a minor potential for use as zinc or
copper ore as is typically associated with Copper deposits including
Limestone which is the source of the Carbonate. |

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.
