Amethyst is a purple variety of Quartz often used as an ornament.
Upon exposure to heat, Amethyst generally becomes yellow, which some refer
to as Citrine or "burnt" Amethyst. It occurs in color from a light,
slightly pinkish violet to a deep grape purple. It is widely distributed
as a mineral, but fine, clear specimens that are suitable for cutting as ornamental
stones.

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

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.

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.

Citrine is any Quartz Crystal or cluster that is yellow or orange in
color. Most Citrine, usually begins as Amethyst which becomes yellow
due to heat treatments. True Citrine is often rarer but is hard to distinguish
from the heat treated variety. It is widely distributed as a mineral,
but fine, clear specimens that are suitable for cutting as ornamental stones.

Goldstone is a type of man-made glass with Copper or Copper salts
made by a reducing flame. The most common form of Goldstone give the
illusion of being a reddish-brown, although in fact the color comes from
the Copper crystals and the glass itself is colorless. Other variants
have an intensely color matrix usually blue or violet, and more rare,
green. |

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.
