Hi there. I am selling these nice natural native copper sphere carving.. .

These would be great for starting your own mineral collection, or for a reiki or crystal healer, or just to have some very beautiful decorations in your house

. They have been washed in sea salt and have been prepared for their new owner.

It is formed from high grade AA++ Top shelf Copper metal,and is from Michigan.

  This sphere weighs 60.55 carats, which is 12.10 grams. .The sphere measures 14 mm across - or thick,

The measurements for this sphere are the DIAMETER of the sphere, in other words the width of the sphere as measured with calipers. This sphere has a flat spot on the bottom to keep it from rolling away. It is a quick way to have a sphere stand built into the item. So it isn’t an actual perfect sphere. The company that makes these spheres creates a flat spot for them all to ‘sit’ on, even the large hand formed 45 mm sphere have a flat spot. This is awesome for some (me, I like this because I prefer the aesthetic of just the sphere in my cabinet with no clunky plastic ring holding it up, but others aren’t as happy because it isn’t an actual perfect sphere. Below is a Wikipedia article about natural copper and the company that made this carving- they also make pyramids and press large one ounce decorative solid copper coins and bullion as well.

  If you have any questions, do not hesitate to ask me.

Have fun bidding, . Thanks so much for visiting my auction and have a great day:>)

The following is a wikipedia entry about copper:


Copper Wikipedia article (link stripped)

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.

A freshly exposed surface of pure copper has a pinkish-orange color.

Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement.

Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals). This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC, the first metal to be cast into a shape in a mold, c. 4000 BC and the first metal to be purposefully alloyed with another metal, tin, to create bronze, c. 3500 BC.[4]

In the Roman era, copper was principally mined on Cyprus, the origin of the name of the metal, from aes сyprium (metal of Cyprus), later corrupted to сuprum (Latin), from which the words derived, coper (Old English) and copper, first used around 1530.

The commonly encountered compounds are copper(II) salts, which often impart blue or green colors to such minerals as azurite, malachite, and turquoise, and have been used widely and historically as pigments.

Copper used in buildings, usually for roofing, oxidizes to form a green verdigris (or patina). Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Copper compounds are used as bacteriostatic agents, fungicides, and wood preservatives.

Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the respiratory enzyme complex cytochrome c oxidase.

In molluscs and crustaceans, copper is a constituent of the blood pigment hemocyanin, replaced by the iron-complexed hemoglobin in fish and other vertebrates.

In humans, copper is found mainly in the liver, muscle, and bone.

The adult body contains between 1.4 and 2.1 mg of copper per kilogram of body weight.

Copper, silver, and gold are in group 11 of the periodic table; these three metals have one s-orbital electron on top of a filled d-electron shell and are characterized by high ductility, and electrical and thermal conductivity.

Copper is one of a few metallic elements with a natural color other than gray or silver.

Pure copper is orange-red and acquires a reddish tarnish when exposed to air. The characteristic color of copper results from the electronic transitions between the filled 3d and half-empty 4s atomic shells – the energy difference between these shells corresponds to orange light.

As with other metals, if copper is put in contact with another metal, galvanic corrosion will occur

Copper is produced in massive stars and is present in the Earth's crust in a proportion of about 50 parts per million (ppm).

In nature, copper occurs in a variety of minerals, including native copper, copper sulfides such as chalcopyrite, bornite, digenite, covellite, and chalcocite, copper sulfosalts such as tetrahedite-tennantite, and enargite, copper carbonates such as azurite and malachite, and as copper(I) or copper(II) oxides such as cuprite and tenorite, respectively.

The largest mass of elemental copper discovered weighed 420 tonnes and was found in 1857 on the Keweenaw Peninsula in Michigan, US!!!!

Native copper is a polycrystal, with the largest single crystal ever described measuring 4.4×3.2×3.2 cm !!!!

Copper has been in use at least 10,000 years, but more than 95% of all copper ever mined and smelted has been extracted since 1900, and more than half was extracted the last 24 years.

As with many natural resources, the total amount of copper on Earth is vast, with around 1014 tons in the top kilometer of Earth's crust, which is about 5 million years' worth at the current rate of extraction. However, only a tiny fraction of these reserves is economically viable with present-day prices and technologies.

Estimates of copper reserves available for mining vary from 25 to 60 years, depending on core assumptions such as the growth rate.[26] Recycling is a major source of copper in the modern world.[25] Because of these and other factors, the future of copper production and supply is the subject of much debate, including the concept of peak copper, analogous to peak oil.

Numerous copper alloys have been formulated, many with important uses.

Brass is an alloy of copper and zinc. Bronze usually refers to copper-tin alloys, but can refer to any alloy of copper such as aluminium bronze.

Copper is one of the most important constituents of silver and karat gold solders used in the jewelry industry, modifying the color, hardness and melting point of the resulting alloys.

Some lead-free solders consist of tin alloyed with a small proportion of copper and other metals.

The alloy of copper and nickel, called cupronickel, is used in low-denomination coins, often for the outer cladding.

The US five-cent coin (currently called a nickel) consists of 75% copper and 25% nickel in homogeneous composition.

The alloy of 90% copper and 10% nickel, remarkable for its resistance to corrosion, is used for various objects exposed to seawater, though it is vulnerable to the sulfides sometimes found in polluted harbors and estuaries.

Alloys of copper with aluminium (about 7%) have a golden color and are used in decorations.

Shakudō is a Japanese decorative alloy of copper containing a low percentage of gold, typically 4–10%, that can be patinated to a dark blue or black color.

History A timeline of copper illustrates how the metal has advanced human civilization for the past 11,000 years.

Prehistoric Copper Age —

Many tools during the Chalcolithic Era included copper, such as the blade of this replica of Ötzi's axe Copper ore (chrysocolla) in Cambrian sandstone from Chalcolithic mines in the Timna Valley, southern Israel. Copper occurs naturally as native metallic copper and was known to some of the oldest civilizations on record.

The history of copper use dates to 9000 BC in the Middle East; a copper pendant was found in northern Iraq that dates to 8700 BC.

Evidence suggests that gold and meteoric iron (but not smelted iron) were the only metals used by humans before copper.

The history of copper metallurgy is thought to follow this sequence: First, cold working of native copper, then annealing, smelting, and, finally, lost-wax casting. In southeastern Anatolia, all four of these techniques appear more or less simultaneously at the beginning of the Neolithic c. 7500 BC.

Copper smelting was independently invented in different places. It was probably discovered in China before 2800 BC, in Central America around 600 AD, and in West Africa about the 9th or 10th century AD.

Production in the Old Copper Complex in Michigan and Wisconsin is dated between 6000 and 3000 BC.

Natural bronze, a type of copper made from ores rich in silicon, arsenic, and (rarely) tin, came into general use in the Balkans around 5500 BC.

Bronze Age —-

Bronze Age Alloying copper with tin to make bronze was first practiced about 4000 years after the discovery of copper smelting, and about 2000 years after "natural bronze" had come into general use.

Bronze artifacts from the Vinča culture date to 4500 BC.

Sumerian and Egyptian artifacts of copper and bronze alloys date to 3000 BC

Copper was first used in ancient Britain in about the 3rd or 2nd century BC. In North America, copper mining began with marginal workings by Native Americans.

Native copper is known to have been extracted from sites on Isle Royale with primitive stone tools between 800 and 1600.

Copper metallurgy was flourishing in South America, particularly in Peru around 1000 AD. Copper burial ornamentals from the 15th century have been uncovered, but the metal's commercial production did not start until the early 20th century.

The cultural role of copper has been important, particularly in currency. Romans in the 6th through 3rd centuries BC used copper lumps as money. At first, the copper itself was valued, but gradually the shape and look of the copper became more important.

Julius Caesar had his own coins made from brass, while Octavianus Augustus Caesar's coins were made from Cu-Pb-Sn alloys. With an estimated annual output of around 15,000 t, Roman copper mining and smelting activities reached a scale unsurpassed until the time of the Industrial Revolution; the provinces most intensely mined were those of Hispania, Cyprus and in Central Europe.

The gates of the Temple of Jerusalem used Corinthian bronze treated with depletion gilding. The process was most prevalent in Alexandria, where alchemy is thought to have begun.

In ancient India, copper was used in the holistic medical science Ayurveda for surgical instruments and other medical equipment. Ancient Egyptians (~2400 BC) used copper for sterilizing wounds and drinking water, and later to treat headaches, burns, and itching. Modern Acid mine drainage affecting the stream running from the disused Parys Mountain copper mines 18th century copper kettle from Norway made from Swedish copper The Great Copper Mountain was a mine in Falun, Sweden, that operated from the 10th century to 1992. It satisfied two thirds of Europe's copper consumption in the 17th century and helped fund many of Sweden's wars during that time.[77] It was referred to as the nation's treasury; Sweden had a copper backed currency.[78]

Copper is used in roofing,[14] currency, and for photographic technology known as the daguerreotype.

Copper was used in Renaissance sculpture, and was used to construct the Statue of Liberty; copper continues to be used in construction of various types.

Copper plating and copper sheathing were widely used to protect the under-water hulls of ships, a technique pioneered by the British Admiralty in the 18th century.[of northern Michigan, primarily native copper deposits, which was eclipsed by the vast sulphide deposits of Butte, Montana in the late 1880s, which itself was eclipsed by porphyry deposits of the Souhwest United States, especially at Bingham Canyon, Utah and Morenci, Arizona. Introduction of open pit steam shovel mining and innovations in smelting, refining, flotation concentration and other processing steps led to mass production.

Early in the twentieth century, Arizona ranked first, followed by Montana, then Utah and Michigan.

Copper in renewable energy Assorted copper fittings The major applications of copper are electrical wire (60%), roofing and plumbing (20%), and industrial machinery (15%).

Copper is used mostly as a pure metal, but when greater hardness is required, it is put into such alloys as brass and bronze (5% of total use).

For more than two centuries, copper paint has been used on boat hulls to control the growth of plants and shellfish.[85] A small part of the copper supply is used for nutritional supplements and fungicides in agriculture.[44][86] Machining of copper is possible, although alloys are preferred for good machinability in creating intricate parts. Wire and cable

Copper wire and cable Despite competition from other materials, copper remains the preferred electrical conductor in nearly all categories of electrical wiring except overhead electric power transmission where aluminium is often preferred.

Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment.[89] Electrical wiring is the most important market for the copper industry. This includes structural power wiring, power distribution cable, appliance wire, communications cable, automotive wire and cable, and magnet wire. Roughly half of all copper mined is used for electrical wire and cable conductors.[91] Many electrical devices rely on copper wiring because of its multitude of inherent beneficial properties, such as its high electrical conductivity, tensile strength, ductility, creep (deformation) resistance, corrosion resistance, low thermal expansion, high thermal conductivity, ease of soldering, malleability, and ease of installation. Copper has excellent brazing and soldering properties and can be welded; the best results are obtained with gas metal arc welding.

Copper is biostatic, meaning bacteria and many other forms of life will not grow on it. For this reason it has long been used to line parts of ships to protect against barnacles and mussels.

Copper-alloy touch surfaces have natural properties that destroy a wide range of microorganisms (e.g., E. coli O157:H7, methicillin-resistant Staphylococcus aureus (MRSA), Staphylococcus, Clostridium difficile, influenza A virus, adenovirus, and fungi).

Copper alloys were proven to kill more than 99.9% of disease-causing bacteria within just two hours when cleaned regularly.[116] The United States Environmental Protection Agency (EPA) has approved the registrations of these copper alloys as "antimicrobial materials with public health benefits";[116] that approval allows manufacturers to make legal claims to the public health benefits of products made of registered alloys. In addition, the EPA has approved a long list of antimicrobial copper products made from these alloys, such as bedrails, handrails, over-bed tables, sinks, faucets, door knobs, toilet hardware, computer keyboards, health club equipment, and shopping cart handles (for a comprehensive list, see: Antimicrobial copper-alloy touch surfaces#Approved products). Copper doorknobs are used by hospitals to reduce the transfer of disease, and Legionnaires' disease is suppressed by copper tubing in plumbing systems.[117] Antimicrobial copper alloy products are now being installed in healthcare facilities in the U.K., Ireland, Japan, Korea, France, Denmark, and Brazil and in the subway transit system in Santiago, Chile, where copper-zinc alloy handrails will be installed in some 30 stations between 2011 and 2014.

Textile fibers can be blended with copper to create antimicrobial protective fabrics.

Folk medicine

Copper is commonly used in jewelry, and according to some folklore, copper bracelets relieve arthritis symptoms.

In one trial for osteoarthritis and one trial for rheumatoid arthritis no differences is found between copper bracelet and control (non-copper) bracelet.

No evidence shows that copper can be absorbed through the skin. If it were, it might lead to copper poisoning.

Compression clothing Recently, some compression clothing with inter-woven copper has been marketed with health claims similar to the folk medicine claims. Because compression clothing is a valid treatment for some ailments, the clothing may have that benefit, but the added copper may have no benefit beyond a placebo effect.
