PR708c
Here is a very nice, above average quality Arizona Petrified Wood End.
It measures 6" x 4" x 2 3/4" and is nicely polished on the front face.
This Wood specimen has good color and design. It has been cut and polished
in the Rock Shed's own Lapidary department. A super great gift.
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.

Here is a very nice, above average quality Ocean Jasper Free Form. It
measures 2" x 1 1/2" x 1 1/2" and has a good polish on all sides. This
specimen has a Green base with White Agate eyes and a sparkly Crystal surface
on one side. Another photo.

The Ocean Jasper deposit, even though it was found only a few years
ago, is nearly gone and the material is becoming hard to find. The deposit
formed as a Rhyolite flow but has been completely silicified. The Rhyolitic
eyes or orbs come in an astonishing array of colors and color combinations.
The back ground can be white, pink, green, red, or yellow. Botryoidal formations
as well as white and deep green druzy are also common. This deposit was discovered
at the edge of the ocean. It can only be seen and collected at low tide. The
area has no road so the material must be transported to civilization by boat.
Several other types of jasper are found there now but the orbicular Jasper
is gone.

This is a very nice Brazilian Agate end cut. It measures approximately
3 1/2" x 6" x 1 1/2" and is polished on the cut side. This Agate
has a nice, natural interior which exhibits a beautiful center with a Tan
and Cream colored Agate design with just a hint of Lavender. A nice display
piece for your collection. Very beautiful. 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.

This is a polished End from an Utah Septarian Nodule. It measures 7
1/2" x 7" x 2 3/4". This one has lots of Brown Aragonite with contrasting
Yellow Calcite. This beauty was cut and polished in the Rock Shed's
own lapidary department. Septarian nodules are rather difficult to find
now, so grab this one while you have the chance. 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.

PR711b Here
is something different from the gift department at the Rock Shed. This
is a larger, hand crafted Soapstone Box with inlaid Abalone shell design.
It measures 5" x 1 1/4" and has a smooth finish. The box has a removable
lid with an intricate hand carved floral design on each side. The inlay
Abalone shell design has a pretty Pink and Blue floral pattern. A perfect
gift for that perfect person. Soapstone, also known as Steatite or
Soaprock, is a metamorphic rock or Talc-Schist. It is composed of the
mineral Talc and is rich in Magnesium and is formed by the metamorphism of
ultramafic protoliths and the metasomatism of siliceous Dolostones.
It is a very soft material and may have a soapy feel when touched. It
can be easily carved into decorative items as well as bowls or other cooking
utensils. It is used by welders and fabricators as a marker due to its
resistance to heat.

Here is something different from the gift shop at the Rock Shed. This
is a very nice, above average quality Uruguayan Agate Amethyst Geode half.
It measures 5 1/4" x 4" x 5" with a natural, rough texture on the outside.
The inside reveals very nice Purple and White Crystals. Very beautiful
indeed. 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, but fine, clear specimens that are suitable for cutting as ornamental
stones.

PR705b Here is a very
beautiful Selenite Free Form resting in a wooden base. The Selenite
measures 6" x 6 3/4" x 1 1/2" and has a natural shine and finish. This
lovely specimen has a translucent appearance and is almost totally clear.
It has an unique shape and design. A great addition to any collection
or a super gift.
Another photo.
Selenite, also known as Satin Spar, Desert Rose and Gypsum Flower, are
the four Crystalline varieties of Gypsum. It is a very soft material
composed of Calcium Sulfate. Selenite is often transparent and colorless.
If color is present it is often due to impurities or presence of other minerals.

Here is something different for the polished rock collector. This
is a very nice, above average quality Dry Head Agate Slab. It measures
6 1/2" x 5" x 1/2" with a nice front face polish. This Agate has a very
nice design and beautiful blend of Earth tone color and an totally awesome
Crystal cavity. Definitely a keeper.
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.

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.

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.

as it comes from the box.
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 of Onyx is found in Mexico and Pakistan. It is often carved, polished
and sold in a variety of different things.

Here is something different for the polished rock or mineral collector.
This is an above average quality polished specimen of beautiful Blue Lapis.
It measures 1 1/2" x 3" x 2" and is highly polished on all sides. This
stand up has a light Blue color with many areas of sparkly Pyrite and Grey
to White Quartz. Another photo.
Lapis is a stone with a long tradition of being considered a gem.
It is usually deep blue in color and is opaque. It is a rock and not
a mineral as it is made up from various other minerals. The main component
is Lazurite which is a Feldspar Silicate. Lapis may also contain Calcite,
Sodalite and Pyrite. It is found worldwide.

This is a very pretty, above average quality, multi-colored Onyx
Vase from Pakistan. This Vase measures 2 3/4" x 3". It is highly
polished all around except for the base. It makes for a very interesting
display piece or would make a nice gift. Marble is a metamorphic
rock consisting of Limestone but mostly composed of Calcite. It is used
extensively for sculpture, building materials and has many decorative uses.
The pure white Marble is probably the most common form known, but the characteristic
swirls and veins of many colored Marble varieties are usually due to various
mineral impurities such as Clay, Silt, Sand, Iron Oxides or Chert.
