Here is a very nice, above average quality Arizona Petrified Wood.
It measures 6 5/8" x 5" x 1" 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 Shell Marble Free Form. It
measures 2 7/8" x 2 1/4" x 1 1/2" and has a good polish on all sides. This
specimen has a unique design that reflects different types of shells or
interesting fossils. You may just want to use it as a paper weight or
conversation piece. Another photo.
Marble is a metamorphic rock consisting of Limestone but composed
mostly 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.

PR702c These
"Chrysanthemum" Flowers, frozen in stone, are natural occurrences of Celestite
crystals in a limestone matrix. Found in Liuyang County, Hunan Province
in China. The Chrysanthemum Stone Flower has been highly prized as a marvel
of nature. Once polished and carved to show the wondrous flower, it
is a soothing object for contemplation and meditation.
The flower measures 3 3/8" x 2 1/2" and rests in matrix measuring
3 /4" x 3 3/4"
x 2 1/4". These make great decorator items.

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.

or a super gift.

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 rare and different for the polished rock collector.
This is a very nice, above average quality Dry Head Agate End Cut from Montana. It measures 4
3/4" x 3 1/4" x 1" with a nice front face polish. This Agate has a very
nice design and beautiful blend of Earth tone color and several small
Crystal cavities. Definitely a keeper.
Another photo.
Dry Head Agates are
from the Bighorn Canyon area of Montana. The banding colors are usually
bright orange with some white or pink bands on charcoal, light gray,
whitish oranges or greenish matrix. Dry Head Agates are very rare and no longer
available as the mining area is now part of a wild horse refuge. Dry Head Agates may be geologically similar to the Teepee Canyon and Fairburn
Agates of the Black Hills area.

Another photo.
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.

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.

from the the display of this neat vase.
