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.

1/4" and makes a unique addition to any
collection.

Chalcopyrite is a copper iron sulfide mineral that crystallizes in
the tetragonal system. Chalcopyrite has a brassy to golden yellow color,
which often resembles Gold. However, its physical properties such as
streak and tenacity are very different from Gold and can easily
distinguish it. Chalcopyrite is a beautiful mineral, with good crystals
being fairly common. Chalcopyrite is rarely found in association with
native copper.
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.

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.

Here is a very nice Green and Watermelon Tourmaline in Quartz specimen from Brazil.
The Watermelon Tourmaline is harder to find and identified as shown by the Pink color in the center
in the linked pictures below. This interesting specimen measures almost
7 3/4" x nearly 4" x almost 4
1/2" and has many, many sparkly
dark Green colored crystals. The two longest Tourmaline crystals
each measures approximately 2 1/8" long. Very nice.

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.

M104c Here is a
very nice Dugway Geode specimen from an unknown location in Utah. It
measures 6 3/8" x 5" x 2 5/8" and is a lovely pale grey color
with some lighter areas inside. This pretty Geode fluoresces a nice
green color in the crystal cavity with a very cool design under short wave
UV light. This pretty Dugway Geode is a beautiful work of nature.

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.

M105b This is
a great find!! Here is an extra nice quality specimen of
Labradorite. It measures 4" x 3" thick x 6 3/8" tall and has a good polish on the face. This lovely Labradorite
specimen has a super color mix with a highly iridescent shine that can be
seen as it's turned in the light better shown in the linked pictures

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.

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.
