This is a polished Slab from an Utah Septarian Nodule. It measures 6"
x 7" x 51/2". This one has lots of Brown Aragonite with contrasting Yellow
Calcite. 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.

Here is something different for any collector. Here is a very nice,
very pretty Selenite Crystal from Utah. It measures 2 3/4" x 2" x 1"
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.

This is a very pretty, above average quality, multi-colored Marble Vase from
Pakistan. This vase measures 3 3/4" x 3 3/4". It is highly polished
all around except for the base. This vase has a very nice, softer Beige
color with Brown and White accents. 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

This is a great find!! Here is an unusual, but interesting Lingam Stone.
It measures 4 3/4" x 2 3/4" and has a smooth surface which does not appear
to have any polish. The Lingam Stones are native to India and the Hindu
religion. This stone came to us with unknown origin. Lingam Stones
have an unique history and are used for Hindu religious ceremonies.

This is a great find!! This is a Los Choyas Geode, broken in half, showing
a full interior of pretty Lavender and White crystals. This above average
quality, whole Geode measures 4 1/2" x 4" in diameter with a rough exterior.
A really nice, but different gift, for the hard to buy for person. This
geode is from Mexico. 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 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 6 1/4" x 4 1/4" x 1 1/2" 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 Morocco. This is an oblong, very unique
geode, broken in half, which shows an interior of Clear to White Quartz Crystals.
The full Geode measures 9 1/2" x 4 3/4" x3 1/2" with a natural, unpolished
exterior. Although it is difficult to view in the photos, close observation
will reveal very nicely formed Quartz Crystals from the breaking point of
both halves all the way to each end of the Geode. Just marvelous!!

This is something different for the polished rock collector. Here is
a larger, polished Slab from a specimen of Brazilian Agate. It measures
4 1/2" 3 1/4" x 7/8" and is polished on one side. This piece has a nice
unique shape, really great design and real unusual color.
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.

Here
is a great find. This is a Rose Quartz pocket piece from Brazil.
Each piece measures approximately 2 3/4" x 1 7/8" x 3/4" and has been polished
all over. Item is similar to photo. You will receive one (1) pocket
piece. 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 nice petrified wood limb round section from Madagascar. It has
been cut and polished on one end to show the true beauty of the interior.
It has the look of a real branch on the exterior. A nice addition to
any rock collection, it is a very colorful specimen measuring 2 3/4" x 3 1/2"
x 3". 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 something really different for the polished rock collector!!
Here is an above average Lapis Free Form from Afghanistan. It measures
2 3/4" x 1 1/2" x 1 1/4" and has been polished on all sides. A very
unique gift. Another photo.
Lapis is a stone with a long tradition of being considered a gem.
It is usually deep blue in color and is opaque. It is a rock and not
a mineral as it is made up from various other minerals. The main component
is Lazurite which is a Feldspar Silicate. Lapis may also contain Calcite,
Sodalite and Pyrite. It is found worldwide.
