PR404b Here is something different here at the Rock Shed. This is an above average quality
Mexican Lace Agate Slab. It measures
9 3/4" x 3 5/8" x 1/2" and has a nice polish on one
side. This
beauty has very nice banding typical of Mexican Lace with a sparkly
crystal cavity in one area. There are several other small cavities
scattered about. This pretty piece was cut and polished here in our
own Lapidary Department. It comes with a plastic display stand. Very nice!

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.

and has a natural shiny appearance. A great conversation piece or use
it wire wrap a new piece of jewelry.

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.

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

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 something different from Mexico. This is a very nice
complete Trancas Geode and has been cracked down the middle to show the
beautiful inside crystals. It measures 2 3/8" x 2 1/4" x
2" when the pieces are together. The inside and outside of the Geode have not
been polished. A true beauty!
Another photo
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.

PR400c This is a nice, above average Laguna Agate slab
with great color and a very unique design. It measures 2 3/8" x
over 1 3/4" x nearly 3/16" and has been polished
on the front face. This is a beautiful work of nature and has great
characteristics especially when held in the bright light. This material is
from Mexico. Another photo

Here
is a great find. This is a Rose Quartz pocket piece from Brazil.
Each piece measures approximately 2" in length x 1" in width and has been polished
all over. Item is similar to photo. You will receive one (1) pocket
piece. These are really beautiful! Rose Quartz is a type of Quartz which exhibits a pale pink
to rose red hue. The color is usually considered as due to trace amounts
of Titanium, Iron or Manganese, in the massive material. Some Rose Quartz
contains microscopic Rutile needles which produce an asterism in transmitted
light.

This
is a really rare item. This is a beautiful Dry Head Agate from
Montana. It has excellent banding colors around the quite small
crystallized cavities. The piece measures approximately 4 5/8" x
nearly 4 5/8" x over 1 5/8" and has been polished on the face. Very cool indeed!

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.

Here
is a very different item here at the Rock Shed. This is a larger, very pretty
Petrified Wood Slab from Wiggin's Fork, Wyoming. This gorgeous specimen
measures approximately 7 1/2" x nearly 4 3/4" x nearly 3 1/2" and has been highly polished
on one side to show the lovely crystallized, nearly clear, colors it is made of. This
piece was cut and polished in our own Lapidary department. A very
unique and beautiful addition
to any rock collection.

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 something different for any collector. Here is
a very nice, very unique Geode. The exterior is much like a Candy
Apple Geode but the inside is much different then most you will find.
The inside has off white colored crystals and remind me of a cave.
The Geode measures nearly 3 3/4" x 2 3/4" x 2 1/4" and has a natural
unpolished appearance. A great conversation piece!

Here is
something different from the gift department at the Rock Shed. This
is a very nice specimen of Youngite from Wyoming.
It measures 4 3/4" x 4 5/8" x over 2 1/2" and has a nice botryoidal
quartz druzy finish on much of it. The exposed Jasper varies in
color from tan to reddish in other areas. The Youngite shows a pretty
green under short wave UV light and purple under long wave as shown.
A perfect gift for that perfect person.

Youngite is an Agatized Brecciated Jasper with a grayish translucent
druzy quartz around the outside of the material. The druzy quartz usually
fluoresces green. The Jasper center color varies from tan to peach, brown,
reddish and salmon. Youngite is used in making gemstone beads or
cabochons and is very hard.
