Here is a very beautiful Tourmaline and Crystal Quartz
specimen. It measures 3" x 3" x 3". This is a natural beauty
that has many single Crystal points with several "petal" like formations of
black Tourmaline interspaced between the Crystals. This is a very wonderful
example of nature at its best. This material is from China.
Tourmaline is one of the most chemically complicated of all Silicate minerals.
It is a complex Silicate of Aluminum and Boron and the composition varies
widely with Sodium, Calcium, Iron, Magnesium, Lithium and many other elements
that enter into it's structure. It can occur in a long, slender needle-like
crystal to a thick prismatic and columnar crystal to a radial like daisy formation.
It comes in many colors usually black and brown (iron rich); brown and yellow
(magnesium rich); and blue, red, green, yellow, and pink (lithium rich).

This is a great find!! Here is an extra nice quality specimen of
Labradorite. It measures 3 1/4" x 2 5/8" x nearly 2 3/4" and has a good
polish on one side. This specimen has a super color mix with a highly iridescent
shine. This would make a great gift for the "hard to buy for" person.

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.

Here is a very different mineral to add to your mineral collection.
This is a very nice quality Moonstone and Biotite specimen from India.
The mineral measures 5 5/8" x 3 3/4" x almost 3 1/4" and has a natural
sparkly appearance. Close observation in bright sunlight will reveal
the blue iridescent areas of the moonstone.
Another photo
Moonstone is a typical Potassium Aluminum Silicate with several commonalities
with the Feldspar family. It's name is derived from the visual effect
or sheen that is caused by light reflecting internally and externally from
the layer inclusions of different Feldspars. Moonstone is closely related
to Sunstone, Labradorite and Sodalite.

This is a larger, but very pretty specimen of unpolished Botryoidal
Malachite from Africa. It measures 7" x 3 1/2" x 2 5/8" tall and has
a natural botryoidal appearance. This is a natural specimen just as
it occurred in nature.
Another photo
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.

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.

This is an interesting mineral combination! Here is an Apophyllite-Stilbite
mix. This fantastic mineral measures 4 1/2" x 3 1/2" x 2" and has a super
sparkly appearance. A great way to begin your mineral collection with
a smaller collection all in one!!
Another photo
Stilbite is another Silicate mineral from the Zeolite family.
It is often characterized by its sheaf like aggregates. The color is
usually white and when the cleavage is perfect, will have a distinct pearly
luster.
Apophyllite, also a Zeolite, is Silicate mineral with very well defined
clear Crystals and is very popular as a collector's mineral. The Crystal
structure will refract like in obvious rainbows and can form "natural pyramids"
when tumbled.

Here is something different for the mineral collector. This is a
larger, very unique Aragonite specimen. It measures nearly 6 1/2" x
3 1/4" x 2 3/8" and has a natural White color. This material has an
interesting shape and lots of sparkly character. The material is usually formed

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 something different for the mineral collector. This
is a very nice group of Spessartine Garnets in matrix. The mineral mix
measures 3 3/8" x 2 5/8" x 1 1/8" and has not been polished. The mineral
has many Bronze colored Garnet Crystals resting with tiny Mica Crystals
in a Pegmatite base. The Green-Grey material is clay based but the exact
name is unknown. Another photo
Garnet is included in a group of minerals that have been used since the
Bronze Age as gemstones and abrasives. Garnets are most often as seen
in red, but are available in a wide variety of colors spanning the entire
color spectrum except blue. There are six common species of Garnet that
are recognized by their chemical composition: Pyrope, Almandine, Spessartite,
Grossular, which includes Hessonite and Tsavorite, Uvarovite and Andradite.

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.

Here is an above average quality of a larger specimen of Hemimorphite Crystals
setting on a dark Rust base of Limonite. It measures 6 1/2" x
3 3/4" x 2" with a natural rough appearance and many differently shaped translucent
Grey and Clear Crystals. A different mineral for the different collector.
This material is from Mexico. 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.
Hemimorphite is a mineral that has been mined with Zinc and Lead ores
and is associated with Smithsonite. Some specimens will show a strong
green fluorescence in short wave UV light and weak light pink fluorescence
in long wave UV light. This mineral can be found world wide.

The Campo Del Cielo Iron Meteorite is from Gran Chaco Gualamba,
Argentina. These Campo meteorites were first found in 1576. It probably
impacted the earth nearly 6000 years ago leaving an extensive strewn field
and more than 12 craters. The Campo Del Cielo Meteorites are a Coarse
Octahedrite, Type 1A, (3mm crystal). They consist of an average
composition of 92% Iron, 6% Nickel and other rare minerals with silicate
inclusions. |

Sandstone is a sedimentary rock composed mainly of sand size mineral
or rock grains. Most Sandstone is composed of Quartz and/or Feldspar
because these are the most common minerals in the earth's crust. It
can be almost any color. The Sandstone beds often form highly visible
cliffs and are strongly identified with certain regions of the world.

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.

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.
