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.

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.

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.

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.

Rhyolite is an igneous, volcanic rock that is composed of
Felsic, or Silicate minerals such as Silica, Aluminum, Sodium and
Potassium. This material, also called Volcanic Tuft and Rainbow Rock
actually began as volcanic ash spewed from the mouth of a volcano millions
of years ago. This ash was exposed to heat and pressure that resulted in
turning it to stone. The bright banded colors are a result of exposure to
high concentrations of iron oxides. The material is similar to that of
Granite, Pumice and Obsidian but due to the cooling process when formed,
Rhyolite did not form any crystals, thus changing the texture of the
material.

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.

Septarian, also know as a type of Concretion, is a volume of sedimentary
rock in which a mineral cement fills the porosity. Concretions are often
ovoid or spherical in shape. They form within layers of sedimentary
strata that has already been deposited. It is composed of a Carbonate
mineral such as Calcite, a Silica such as Chert, Flint or Jasper or an Iron
Oxide such as Goethite or Hematite. It is commonly found in Shale, Siltstones
and Sandstones.

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.

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.

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.

Fluorite, also referred to as fluor-spar, is a mineral composed
of Calcium Fluoride. It is a widely occurring mineral found world wide and
is often found with metallic minerals such as Galena, Sphalerite, Barite,
Quartz and Calcite. Fluorite may fluoresce strongly in ultraviolet light
which may be due to the presence of some impurities such as Yttrium. Blue
is the most common color but red, purple, green, yellow and white are also
frequent. It can be used in high performance telescopes, camera lens,
enamels and in the making of opalescent glass. |
