This is a very nice Brazilian Agate end cut. It measures approximately
3 3/4" x 3 1/2" x 1" and is polished on the front face. This Agate
has a nice, natural interior which exhibits a beautiful Crystal like center
with a Tan and Beige Agate design. 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 nice larger Petrified Wood specimen from
Arizona.
It measures 7" x nearly 4 3/4" x 4" and has been polished
on one side. This Petrified Wood specimen has rich Grey
and Brown with Red and other colors mixed in with an unique design.
It has been cut and polished in the Rock Shed's own Lapidary department.
The specimen has cracks or fractures that
are common for Petrified Wood material.
A truly beautiful piece of polished Wood.

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 excellent example of Dogtooth Phantom Calcite from Mexico.
It has many very nice scalenohedral or "dogtooth" calcite crystals, mostly
of a dark
Burnt Orange color. This cool specimen shows a gorgeous red
fluorescent color under short wave UV light laid upside-down. It measures 8" x
nearly 3 3/4" x 2 1/4" and has a natural sparkly appearance. A true wonder of
nature. Another

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.

Here is a very nice, above average quality vase made from Marble. It
measures over 5" x 9 3/4" tall and has a nice exterior polish. This vase
has an unique design which exhibits several colors and designs in different
areas of the vase. Definitely a one-of-a- kind treasure.

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. This type of Marble will often have
small animal like creature fossils throughout the matrix or media.

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 something new at the Rock Shed. This is a very nice, above average
quality Brazilian Agate end cut. It measures over 4 1/4" x 3
1/2" and nearly 2" thick with a nice polish on one side. The Agate slab has
nice a dark Brown outer color with a cool pale yellow tinted crystallized center
cavity. Nice!

The Amazonite has a nice light Turquoise color with tiny White sparkly
accents. A true beauty.

Amazonite is a green variety of Feldspar. The name is taken from
that of the Amazon River, from which certain green stones were formerly
obtained, but it is doubtful whether green Feldspar occurs in the Amazon
area. It is a mineral of limited occurrence but is often associated with
smoky Quartz, Orthoclase and Albite in a coarse Granite or Pegmatite.
Because of its bright green color when polished, Amazonite is sometimes
cut and used as a gemstone, although it is easily fractured. |

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.

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.

This is something different from the Rock Shed's gift department. Here
is a very nice, above average quality, hand-made Jasper Arrow Head.
Each Arrow Head measures 4" x 1 1/2" and has not been polished. A very
unique gift for that hard-to-buy-for person. Item will be similar to
items in the photo. We do recommend
caution when considering your purchase as Jasper is a naturally
SHARP
material and may not be acceptable for small children due to the
SHARP
edges the Arrow Heads may have.
Jasper, or spotted stone, is an opaque, impure variety of Quartz that is
usually red, yellow or brown in color. Some Jaspers simultaneously exhibit
