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.

Malachite is a Copper Carbonate mineral that often forms botryoidal, fibrous or stalagmitic masses. It is often the result of the weathering of Copper Ores and is commonly found with Azurite, Goethite and Calcite. It is typically associated with Copper deposits including Limestone which is the source of the Carbonate. Malachite is found in many regions world wide and is usually shaded green in color.

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.

Scolecite is usually colorless or white, but can also be pink, salmon, red or green. It is transparent to translucent, with a white streak and a luster which is vitreous, or silky for fibrous specimens. Scolecite is a common Zeolite often found with associated minerals including quartz, apophyllite and stilbite.

Celestite is a mineral form of Strontium Sulfate which is a metal. The metal is mixed with Carbon and Sulfur which is used for the red "fire" in fireworks, flares and road signals. Celestite occurs as Crystals and in compact massive and fibrous forms. It is mostly found in sedimentary rocks and is often associated with Gypsum, Anhydrite and Halite. Pale blue Crystal specimens are found in Madagascar.

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. 

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.

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.

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.

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.

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.
