Orthoceras is a genus of extinct Nautiloid Cephalopod.  These fossils are common and have a global distribution which occur in any marine rock, especially Limestone.  These are slender, elongated shells with the middle of the body chamber transversely constricted and a sub-central orthochoanitic siphuncle.  The surface is ornamented by a network of fine lirae or fine lines/ridges.

Geodes are geological rock formations which occur in sedimentary and certain volcanic rocks.  They are essentially rock cavities or vugs with internal Crystal formations or concentric banding.  The exterior is generally Limestone while the interior contains Quartz Crystals and/or Chalcedony deposits.  If the Geode is completely filled with Crystal, being solid all the way through, it is then called a nodule.

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.

Septarians are commonly composed of a carbonate mineral such as Calcite, a microcrystalline form of Silica as in Flint or Jasper, or an Iron Oxide such as Hematite.  These specimens are also known as a concretion which is a type of sedimentary rock. Septarians were formed millions of years ago by sediment forming around a fossil to create a mud ball transforming the fossil into Calcite and Aragonite.

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.

This material is a new find from Madagascar. The deposit formed as a rhyolite flow but has been completely silicified. The Rhyolitic eyes or orbs come in an astonishing array of colors and color combinations. The back ground can be white, pink, green, red, or yellow. Botryoidal formations as well as white and deep green druzy are also common. This deposit has been discovered at the edge of the ocean. It can only be seen and collected at low tide. The area has no road so the material must be transported to civilization by boat.  This material is fast becoming a rarity in the Jasper ocban fields, so get one while it is still available.

Onyx is a banded variety of Calcite.  The colors of its bands range from white to almost every color except shades of purple, blue and black.  It is used for vases, bowls, beads, cabochons and other items.  This type is found in Mexico and Pakistan and is often carved and polished into various items.  This material is much more readily available and softer than the gemstone commonly called Black Onyx which is a silica gem.

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.
