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.

PR501c Here
is something different from the gift department at the Rock Shed. This is
an exceptional Petrified Wood stand up from Indonesia. The Petrified Wood is highly polished
on the front face leaving the back side in it's natural state. The polish
not only brings out the gorgeous rich colors but shows the the grain of
the wood. This lovely piece measures
7 5/8" x 3 1/2" x 8 1/8" tall, weighs nearly 9 3/4
pounds and stands perfectly on it's own. A perfect gift for that perfect person.

Petrified Wood is a type of a fossil as it consists of fossil wood where
all the organic materials have been replaced with minerals while retaining
the original structure of the wood. These minerals are most often Silicates
such as Quartz. Other minerals, Manganese, Iron and Copper, in the water
or mud during the petrification process give Petrified Wood a variety of color
ranges: black - Carbon; green/blue - Copper; red/brown/yellow - Iron.
Petrified Wood can preserve the original structure of the wood in all its
detail all the way down to the microscopic level. Structures such as
tree rings and the various tissues are often observed features. Although
Petrified Wood can be found worldwide, it is rather rare in larger quantities
and at times can be difficult to obtain by the average collector.

Rose Quartz is a type of Quartz which exhibits a pale pink to rose red
hue. The color is usually considered as due to trace amounts of Titanium,
Iron or Manganese, in the massive material. Some Rose Quartz contains
microscopic Rutile needles which produce an asterism in transmitted light. |

Onyx is a banded variety of Calcite. The colors of its bands range
from white to almost every color except shades of purple, blue and black.
It is used for vases, bowls, beads, cabochons and other items. This
type is found in Mexico and Pakistan and is often carved and polished into
various items. This material is much more readily available and
softer than the gemstone commonly called Black Onyx which is a silica gem.

PR506b Here is an
amazing discovery! This is a Meteorite from Sikhote-Alin in Martime
Territory near Vladivostok in Russia that fell to earth on February 12,
1947. It measures 1 7/8" x 3/4" x 3/8" thick, weighs 17.5 grams and has a
natural sheen on the Black metallic finish. These Meteorites are special
in that they have "finger print" marks on the surface which are the result
of the melting of the material upon entering the atmosphere from outer
space. A cool gift or just keep it for yourself.

A Meteorite is a natural object originating in outer space that survives
an impact with the Earth's surface without being destroyed. There are
3 types of meteorites: stony, which are mainly composed of Silicate minerals;
Iron, which are largely composed of metallic Iron-Nickel; and stony-Iron,
which are composed of both types of media.

This is an enormous and
very nice Dugway Geode from Utah and from an old collection we recently
purchased. The inside of the lovely irregular cavity is lined with a
variety of different textures from
fine druzy Quartz Crystals with a pale gray, pink and clear crystals. The awesome Dugway Geode has a highly
polished
finish on the cut face with the balance left natural. It measures
7 7/8" wide x 6 5/8" x 2 5/8" thick and weighs nearly 5 pounds. It fluoresces a
pretty green with some blue and a hint of orange under Short Wave UV
light and a gorgeous blue under a LW/UV light . A must have for the collector or an
excellent gift for someone!

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.

Agates mostly occur as nodules in volcanic rocks
or waters containing Silica in solution which is possibly derived from the
decomposition of Silicates in the lava. The Siliceous matter is deposited
in regular layers resulting in the banded or striped formation. It is
very unlikely that you would ever find an exact duplicate of any type
of Agate, Brazilian or other.

Septarians are commonly composed of a carbonate mineral such as Calcite,
a microcrystalline form of Silica as in Flint or Jasper, or an Iron Oxide
such as Hematite. These specimens are also known as a concretion which
is a type of sedimentary rock.
Septarians were formed millions of years ago by sediment forming around
a fossil to create a mud ball transforming the fossil into Calcite and Aragonite.

Jasper, or spotted stone, is an opaque, impure variety of Quartz that
is usually red, yellow or brown in color. Some Jaspers simultaneously
exhibit several variants such as banding, flow patterns, dendrites or color
variations. This results in what appears to be scenes or images in a
cut section of the Jasper.

A limb cast is a psuedomorph where the
original wood has been replaced by chalcedony. These pieces form when a tree was buried by ash. The wood is burned away by
the hot ash and a "cast" is left. Minerals in the groundwater then
permeated the cast, replacing the original organic matter and turning it
to stone. The result is a rock that has the form of a tree limb. Some of
these casts show the bark and wood textures. Pink and green limb casts are
highly prized by collectors. |

Fluorite, also known as fluor-spar, is a mineral
composed of Calcium Fluoride. It is a widely occurring mineral and is
often found with metallic minerals such as Galena and Sphalerite, but also
with Barite, Quartz and Calcite. It may fluoresce strongly in ultraviolet
light. Although blue is the most common color, it can also be red,
purple, green, yellow and white.

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. |

Amethyst is a purple variety of Quartz often used as an ornament.
Upon exposure to heat, Amethyst generally becomes yellow, which some refer
to as Citrine or "burnt" Amethyst. It occurs in color from a light,
slightly pinkish violet to a deep grape purple. It is widely distributed
as a mineral.
