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, Fairburn or other.

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.

Amazonite is a green variety of Feldspar. The name is taken from
that of the Amazon River, from which certain green stones were formerly
obtained, but it is doubtful whether green Feldspar occurs in the Amazon
area. It is a mineral of limited occurrence but is often associated
with smoky Quartz, Orthoclase and Albite in a coarse Granite or
Pegmatite. Because of its bright green color when polished, Amazonite
is sometimes cut and used as a gemstone, although it is easily
fractured. |

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.

of copper ore. Some associated minerals are Quartz, Limonite,
Azurite, and Malachite and Chrysocolla is often confused with Turquoise
as they are similar in color. It gets it's name from Greek chrysos
"gold" and kolla "glue". It is known among Native American cultures as
a healing stone and said to promote calm and level headedness. |

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 |

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. |

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.

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. |

Sardonyx is a form of Chalcedony. Chalcedony is a
cryptocrystalline form of silica, composed of very fine intergrowths of
the minerals quartz and moganite. Chalcedony has a waxy luster, and may be
semitransparent or translucent. It can assume a wide range of colors, but
those most commonly seen are white to gray, grayish-blue or a shade of
brown ranging from pale to nearly black.
