Prehnite is a Phyllosilicate mixture of Calcium and Aluminum.
Although it is not a Zeolite, it is often associated with them and with
Datolite and Calcite, in veins and cavities of Basaltic rocks, sometimes
in Granites, Syenites or Gneisses. The color varies from light green to
grey to white to yellow or a mix of colors. It is translucent and was
named after it's discoverer, Colonel Hendrik von Prehn.

M105b This is
a great find!! Here is an extra nice quality specimen of
Labradorite. It measures almost 4 1/2" x nearly 3 1/2" x 1
1/4"
thick
and has a good polish on one surface with the balance left natural. This specimen has a super color
mix with a highly iridescent shine that can be seen on the unpolished
surfaces as well. 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.

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.

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.

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.

Hemimorphite is
a sorosilicate mineral that is chiefly associated with Smithsonite.
It commonly forms crystalline crusts and layers and also massive, granular,
rounded aggregates or finely shaped clusters of crystals. It may fluorescence
a strong green in UV short wave light and weak pink in UV long wave light.

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.

Vanadinite is a mineral belonging to the Apatite group of Phosphate
minerals. It is one of the main industrial Ores of the metal Vanadium and
a minor source of Lead. Vanadinite is relatively uncommon and is
associated with Galena, Wulfenite, Limonite and Barite. It is usually
bright red or orange-red in color although it may sometimes be brown,
red-brown, grey, yellow or colorless. |

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.
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.

Sandstone like this
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.

color with a very unusual spot of pale blue where the Calcite is under short wave UV
light. This 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.
