$130.00 SP705c  Here is a smaller, very pretty Ocean Jasper sphere.  This sphere has beautiful color scheme and unique design.  Ocean Jasper is mined off the coast of Madagascar in the Indian Ocean.  This sphere measures 3" and has a nice polish.  What a lovely addition to your collection.

The Ocean Jasper deposit, even though it was found only a few years ago, is nearly gone and the material is becoming hard to find.  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 was 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.  Several other types of jasper are found in that area now but the orbicular Jasper is gone.

$45.00 SP703c  Here is a very nice, above average quality Crystal Quartz sphere.  It measures 2 1/2" in diameter and has a nice polish.  The sphere is semi-translucent and has many areas of sparkly, shiny iridescence. Crystal Quartz is very difficult to photograph but this sphere is a true beauty at its best.

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.

$35.00 SP706b   Here is a very nice, natural Galena or Lead Ore sphere. It measures 2" and has been hand ground and polished therefore close observation will reveal some flat areas with some external fractures.  Something very different for your sphere collection.

Galena is the natural mineral form of Lead Sulfide.  It is the most important Lead Ore mineral. Galena is one of the most abundant and widely distributed sulfide minerals. I t crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals Sphalerite, Calcite and Fluorite.

$35.00 SP700b  Here is a very nice, above average quality Rhyolite sphere.  It measures 2 3/4" in diameter and has a nice polish.  This is a very interesting sphere in that it has a very detailed swirled design.  A one-of-a-kind sphere.

Rhyolite is an igneous, volcanic rock that is composed of Felsic, or Silicate minerals such as Silica, Aluminum, Sodium and Potassium.  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.

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.

SP707c   Here is something different for the sphere collector!  This is a very nice, above average quality Pyrite sphere.  This material is from Peru.  The sphere measures just over 1 1/2" in diameter and has a smooth, semi-polished finish.  This sphere has a sparkly, shiny appearance and several very unique Crystal cavities that add to it's character.

Another photo.

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.

$160.00 SP708c   Here is a very unique sphere!   This is a beautiful sphere was cut from a Brazilian Agate Geode.  The outside shows the different colors of the rind of the agate and the inside has a gorgeous light purple colored Crystal cavity that goes nearly all the way through.  This awesome sphere is nearly 3 1/4" in diameter. An excellent and unique addition to any sphere collection.

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.

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.

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.

$22.00 SP710c   Here is a nice Blue Calcite sphere.  This sphere measures 2 1/4" and has a good polish.  It has a shaded Blue and White color that is just beautiful.  This material is from Madagascar.

Another photo.

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.

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.

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.  This type of Marble will often have black, white and grey stripes that resemble a zebra pattern.

Chrysocolla is a Copper Silicate mineral and is associated with minerals such as Quartz, Limonite, Azurite, Malachite and other secondary Copper minerals.  It has an attractive blue-green color that is used as an ornamental stone.  It is typically found as botryoidal or rounded masses and crusts, or vein fillings.  Because of its light color, it is sometimes confused with Turquoise and often can be considered gem quality when translucent and of high quality.
