Sardonyx is a form of Chalcedony. Chalcedony is a cryptocrystalline form of silica, composed of very fine intergrowths of the minerals quartz and moganite. Chalcedony has a waxy luster, and may be semitransparent or translucent. It can assume a wide range of colors, but those most commonly seen are white to gray, grayish-blue or a shade of brown ranging from pale to nearly black.

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.

Sodalite is a rich royal blue mineral enjoyed as an ornamental stone. Although massive samples are opaque, Crystals are usually transparent to translucent. It is very similar to Lapis but without the Pyrite Crystals and distinguishable color differences. It makes great jewelry, cabochons and beads.

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.

This material is a relatively 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 ocean fields, so get one while it is still available.

Scolecite is a hydrated calcium silicate mineral belonging to the Zeolite group. It commonly occurs as sprays of thin, prismatic needles, frequently flattened on one side. 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.

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. 

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.

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.

Sandstone is a sedimentary rock composed mainly of sand size mineral or rock grains. Most Sandstone is composed of Quartz and/or Feldspar because these are the most common minerals in the earth's crust. It can be almost any color. The Sandstone beds often form highly visible cliffs and are strongly identified with certain regions of the world.

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.

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.

Opal is a colorful mineral of hydrated form of Silica related to Quartz. It's internal structure makes it diffract light, taking on many colors depending on the conditions when it was formed. Those colors can range from clear through white, red, orange, yellow, green, blue, purple, rose, pink, brown and black. Opal varies in optical density from opaque to semi-transparent. Opal is the national gemstone of Australia, a producer of over 93% of the world's supply.

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.
