This is an awesome specimen of Petrified Wood
from South Dakota. It has a beautiful array of Brown colors
in the highly polished face accented by various different
textures around the edge. The nice polish brings out the wonderful
character of the wood showing the true beauty. This Petrified Wood
measures 11 3/8" across the widest x 6 1/2" x 2 1/4" thick and weighs
nearly 8 1/2 pounds. This one-of-a-kind piece was created right here in our
Lapidary Department. The piece is actually darker than appears in the
photo. Exceptionally nice!

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. |

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.

Here is an amazing
discovery! This is a very nice half of a Las Choyas or Mexican
Coconut Geode that has been cut to show the beautiful Quartz crystals
inside. The pretty geode half measures 4" x 3 1/2"
x almost 2" thick and has a nice polish on the face. This geode is from Chihuahua, Mexico. Very nice!

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.

Here is a very nice piece of Petrified Wood from the Black Hills of
South Dakota. It measures 5 1/2" x over 3 1/4" x almost 2 1/4" and
has a polished finish on the surfaces. It has a great design, a nice
variety of different Brown colors with lots of character.
As you can see from the photos there are some fractures but they do not
affect the stability of this piece. This awesome example was polished in our own
Rock Shed Lapidary section.
The pictures don't show the true beauty!

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.

Malachite is a Copper Carbonate mineral that often forms botryoidal,
fibrous or stalagmitic masses. It is often the result of the weathering
of Copper Ores and is commonly found with Azurite, Goethite and Calcite.
It is typically associated with Copper deposits including Limestone which
is the source of the Carbonate. Malachite is found in many regions world
wide and is usually shaded green in color.

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.

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.

Garnet is included in a group of minerals that have been used
since the Bronze Age as gemstones and abrasives. Garnets are most often as
seen in red, but are available in a wide variety of colors spanning the
entire color spectrum except blue. There are six common species of Garnet
that are recognized by their chemical composition: Pyrope, Almandine,
Spessartite, Grossular, which includes Hessonite and Tsavorite, Uvarovite
and Andradite.

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.

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.

Rhodenite is a Manganese Silicate material that is commonly a rose-red
color. Rough unpolished specimens have a tendency to turn brown due to
surface oxidation. It is often worked as an ornamental stone as true
Crystals are rare to find. |
