$55.00 SP1010b  This is a pretty Crystal Quartz sphere with a good polish.  The sphere measures 2 1/4" and has a nice polish.  It has a nice almost totally translucent appearance and displays well.  A very nice, hard-to-find type of sphere.

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.

$190.00 SP1004b  Here is a very pretty Ocean Jasper sphere.  The sphere has a several small, external cavities and a beautiful dark Green color with Cream and Olive Green colored highlights.  It is a nice quality sphere and has been hand polished.  It measures 2 3/4" in diameter.  A beautiful sphere that exhibits nature at its best.

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.

$30.00 SP1011c   This is a beautiful Black Obsidian sphere. It measures 2 1/4" in diameter and has an excellent polish.  This material is from Mexico.  The sphere has a unique Silver Sheen appearance at both ends of the sphere.  It makes the sphere very glossy and shiny.  Definitely one in a million.

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.

$25.00 SP1012b  Here is something different from the gift department at the Rock Shed.  This is an very interesting sphere carved from Jet.  It measures 2 1/2" in diameter and has a nice polish.  The sphere has a rich Black color with sparkly highlights.  Definitely something different for the sphere collector.

Jet is a geological material that is not considered a mineral but rather a mineraloid derived from decaying wood under extreme pressure making it organic in origin.  It comes in two forms, hard and soft.  It is easily polished, although is not usually found in that form.  It is also known as Gagate and is a derivative of Coal.

$42.00 SP1008b  Here is a real nice, and very interesting Pyrite sphere.  It measures 2" in diameter.  These sphere are hand polished.  This sphere has a larger, very pretty cavity which shows several Pyrite crystals.  A really neat sphere.

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 is an opaque, impure variety of Quartz that is usually red, yellow or brown in color.  It breaks with a smooth surface and is used for ornamentation or as a gemstone.  It can be highly polished and is used for vases, seals, jewelry and other items such as sphere, eggs, etc.

$40.00 SP1006c  This is a very nice and really interesting Fossil Rock sphere.  It measures 4" in diameter and has a very nice polish.  This sphere has many very well defined fossils that resemble clams, oysters and squids.

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.

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.

SP1009c   Here is a pretty dark Orange Calcite sphere with a larger area of Green Epidote.  This material is from Madagascar.  It measures in at 3 1/4" and has a nice polish and has a very sparkly appearance. Super quality and super nice.

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.
