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.

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.

Chrysocolla is of secondary origin and forms in the oxidation zones 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.

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.

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.

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.
