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
Brazilian Agate. This cool specimen measures 3 1/8" x 2 5/8" x 1
3/4" and has a nice polish on one side.
It has a great design, various beautiful Tan, Grey and Reddish Brown colors
and a nice cavity that goes all the way through.
It makes for a very interesting
display piece or would make a nice gift.

Agates mostly occur as nodules in volcanic rocks or waters
containing silica in solution 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.

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.

This is a very nice specimen of a
Nebraska Chalcedony or often called
Nebraska Blue Agate from western Nebraska. It has nice rich blue
and dark grey to black Earth Tone colors and a neat natural texture on the unpolished surfaces. It
exhibits a bright Green under short wave UV light. The
pretty agate measures nearly 4 3/8" x 3 1/2" x 2" thick and has a
smooth highly polished face. Nebraska Blue Agates are no longer
available from where they were originally found. This wonderful
example was cut and polished in our own lapidary department. This
beautiful Blue Agate is unique and would enhance any table or desk top and
would be a cool gift!

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.

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

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.

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.

Dendrites are branched or tree like inclusions, usually
manganese or iron oxides that are caused by irreversible aggregation of
small particles forming large cluster. It has only been in recent years
that researchers have begun to understand how dendrites form and these
ideas were developed by chemists and mathematicians working in disciplines
called chaos and fractal geometry. Colloidal-sized particles move in
random paths in a phenomenon called Brownian motion.

PR710b This
is a very nice polished Turtle carved from a Septarian Nodule from
Madagascar. This
particularly nice Septarian Turtle has lots of bright Yellow Calcite with contrasting
Brown Aragonite with lots of character.
It measures 4 3/8" wide x 6 5/8" x 2 3/4" tall and weighs
almost 3
1/4 pounds. Septarian nodules, especially
nice ones like this 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.

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.

Copper is a reddish colored metal with a high electrical and thermal
conductivity. It has its characteristic color because it reflects red
and orange light and absorbs other frequencies in the visible spectrum due
to its band structure. It is in the same family as Silver and Gold and
is a malleable metal. It is beautiful natural or polished.

Peacock Marble is from Southwest China and formed in Limestone by
heat and pressure in the earth's crust. Recrystallization during Himalaya
formation caused the limestone to change in texture and makeup. Fossilized
materials along with it's original carbonate minerals, recrystallized and
formed large, coarse grains of calcite. Impurities present in the
limestone during the recrystallization affected the mineral composition of
the marble. The minerals that result from the impurities give the
marble up to ten different colors. The corresponding colors and minerals
that can be found: Green - Serpentine; Purple - Manganese spar; Brown -
Iron; Gray - Silicon Dioxide; Red - Hematite; Orange - Iron; White -
Calcite; Violet - Iron Manganese; Yellow - Limonite; Blue - Copper,
Cobalt, Chromium; Black - Carbon, Iron, Manganese. Peacock Marble is also
called "seven color Jade" in local language.

Amethyst is a purple variety of Quartz often used as an ornament.
It occurs in color from a light, slightly pinkish violet to a deep grape
purple.
Upon exposure to heat, Amethyst generally becomes yellow, which some refer
to as Citrine or "burnt" Amethyst. It is widely distributed
as a mineral, but fine, clear specimens that are suitable for cutting as ornamental
stones.

This is a similar to like item as they are all
very close to appearance and size.
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.
