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 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.

Pinolith or Pinolite, referred to as a type of Jasper but is actually a mixture of Dolmite, Magnesite and Graphite.  Pinolith, a rather newer material is rare.  It is only found in one location, a small manganese quarry in Styria, Austria.  Characteristics are wild and very defined White crystal shapes against a black background.  Some even comparing them to M.C. Escher pencil drawings.  Pinolith has a soft and subtle chatoyant quality.  It has a Mohs hardness of 4 (harder than Calcite but softer than Obsidian.)

Serpentine is a group of common rock forming hydrous Magnesium Iron Silicate minerals.  It can contain minor amounts of Chromium, Manganese, Cobalt or Nickel.  Serpentine may refer to over 20 different varieties that belong to the Serpentine group and the most common are Antigorite, Chrysotile and Lizardite.  The color is often green and may have a mottled or scaly appearance.

SP104b Here is something different for the sphere collector!  This is a very nice, totally Black Obsidian sphere with a smooth, highly polished mirror like finish.  This sphere measures approximately 3 1/2" in diameter and has a character all it's own.

This is a similar to like item as they are all very close to appearance and size.

Obsidian is a type of naturally-occurring glass formed as an extrusive igneous rock.  It is produced when felsic lava erupted from a volcano, cools rapidly through the glass transition temperature and freezes without sufficient time for Crystal growth.  Because of the lack of Crystal structure, Obsidian blade edges can reach almost molecular thinness, leading to its ancient use of projectile points (arrow heads), and its modern use as surgical scalpel blades.

Rhodocrosite is a Manganese Carbonate mineral.  It is typically a rose-red color, but impure specimens can be shades of pink to pale brown.  It is used as a key component of low-cost stainless steel and certain Aluminum alloys.  Quality banded specimens are often used for decorative stones and jewelry, although it is relatively soft and difficult to cut.

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.

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.

Coral is built by secreting calcium carbonate skeletons. Hard coral is fossilized over millions of years.  It can be almost any color.  The stony Corals are often found in Coral reefs, large structures generally found in tropical waters.  Reefs are extremely diverse consisting of over 4,000 species of fish, cnidarians, mollusks, crustaceans, and other animals.

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.

Dendrites are branched or tree like inclusions, usually manganese or iron oxides that are caused by irreversible aggregation of small particles forming large cluster. Dendritic crystal growth is common and resembles a snowflake formation or frost patterns on a window. Dendritic crystallization forms a natural fractal pattern. The term "dendrite" comes from the Greek word dendron, which means "tree". It has only been in recent years that researchers have begun to understand how dendrites form and these ideas were developed by chemists and mathematicians working in disciplines called chaos and fractal geometry. Colloidal-sized particles move in random paths in a phenomenon called Brownian motion.

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.

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.

Moonstone is a typical Potassium Aluminum Silicate with several commonalities with the Feldspar family. It's name is derived from the visual effect or sheen that is caused by light reflecting internally and externally from the layer inclusions of different Feldspars. Moonstone is closely related to Sunstone, Labradorite and Sodalite.

Tourmaline is one of the most chemically complicated of all Silicate minerals. It is a complex Silicate of Aluminum and Boron and the composition varies widely with Sodium, Calcium, Iron, Magnesium, Lithium and many other elements that enter into it's structure. It can occur in a long, slender needle-like crystal to a thick prismatic and columnar crystal to a radial like daisy formation. It comes in many colors usually black and brown (iron rich); brown and yellow (magnesium rich); and blue, red, green, yellow, and pink (lithium rich). This mineral is found in igneous rocks, like Granite Pegmatite, and metamorphic rocks such as Schist and Marble.

Agates mostly occur as nodules in volcanic rocks or waters containing silica in solution 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.

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.

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 an ornamental stone, but fine, clear specimens that are suitable for cutting are used in jewelry.
