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 gives 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.

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.

Aragonite is a Carbonate mineral that can occur in conjunction with Calcium Carbonates.  Aragonite differs from Calcite in the formation of the Crystal shapes which can be in lattice, crystal, columnar or fibrous in many different designs, shapes and sizes.  Aragonite will form in mollusk shells, oceans and salt water caves as inorganic precipitates called marine cements and speleotherms.  Ammolite is a form of Aragonite with impurities that make it iridescent and valuable as a gemstone.

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.

Ammonites are an extinct group of marine animals of the subclass Ammonoida in the class Cephalopoda, phylum Mollusca.  They are excellent index fossils which are fossils that are used to define and identify geologic periods.  Ammonites' closest living relative is probably not the modern Nautilus (which they outwardly resemble) but rather the subclass Coleodiea, which are octopus, squid and cuttlefish.
