Pyrite, or Iron Pyrite, is an Iron sulfide with isometric Crystals that usually appear as cubes.  It is brittle and can break or powder easily.  Its metallic luster and brass yellow hue have earned it the nickname of "fool's gold" due to many miners mistaken it for the real thing.  Ironically, small quantities of actual gold are sometimes found in Pyrite.  It is the most common of the sulfide minerals and is usually found with other sulfides or oxides in Quartz veins, sedimentary or metamorphic rocks.

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.

Tiger-eye is a member of the quartz family, a cryptocrystalline variety.  It is one of the chatoyant varieties of gemstones.  Due to the fibrous structure of the gemstone, as light reflects within the thin parallel fibrous bands it exhibits a changeable silky luster or chatoyancy.  It occurs naturally in colors of gold and blue.

Carnelian is a red or reddish-brown variant of Chalcedony but also may come in the colors of orange and pink.  It is quite common and usually found in translucent pebble form.  It is found in several areas of Europe, Iceland and Madagascar.

Fluorite, also known as fluor-spar, is a mineral composed of Calcium Fluoride.  It is a widely occurring mineral and is often found with metallic minerals such as Galena and Sphalerite, but also with Barite, Quartz and Calcite.  It may fluoresce strongly in ultraviolet light.  Although blue is the most common color, it can also be red, purple, green, yellow and white.

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.

 Chert is a fine-grained silica-rich microcrystalline, that may contain small fossils. It varies greatly in color but most often is  gray, brown, grayish brown and light green to rusty red; its color is an expression of trace elements present in the rock, and both red and green are most often related to traces of iron.

Marble is a metamorphic rock consisting of Limestone but composed mostly 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 or Chert.

Stromatolites are one of the oldest bacterial microfossils known.  The Peruvian Stromatolites are from the lower Proterozic period some 2.3 billion years.  They are from the Eastern Andes, Bolivia, South America.

Calcite is a Carbonate mineral that is most widely distributed on the Earth's surface.  It is a common constituent of sedimentary rocks with Limestone in particular.  A Calcite formation can take on many different shapes and sizes which is dependent on the location, ground water occurrence and temperature.  Calcite is usually white or colorless but can be gray, red, yellow, green, blue, violet, brown or black.  The deeper the color is usually indicative of the definitive impurities from the earth or water.

SP202b This is a very different and nice Stromatolite sphere made from material from England.  It measures approximately 2 5/8" in diameter and has a nice polish.  The sphere has lots of fossil segments and parts and will display nicely.  A great sphere at a great buy.

Stromatolites are one of the oldest bacterial microfossils known. The Peruvian Stromatolites are from the lower Proterozic period some 2.3 billion years. They are from the Eastern Andes, Bolivia, South America.  Stromatolites are actually mounds of mud that have been preserved. Very few will actually contain the fossilized microbes that built them. They accumulate because blue- green algae produces a sticky film that catches mud and silt, in turn forming layers. In time theses layer build up to form mounds.
