Gold has been associated with the extremities of utmost evil and great sanctity throughout history. On the other hand in the Book of Genesis, Abraham was said to be rich in gold and silver, and Moses was instructed to cover the Mercy Seat of the Ark of the Covenant with pure gold.

One of the wise men gave gold as a gift to Jesus when he was born. After the price of gold passed the mark of 1, US dollars per ounce for the first time in March , by the end of it had already reached 1, US dollars per ounce.

Investments in gold are seen as a safe haven and a crisis-resistant capital investment. It is possible to invest in the yellow precious metal both in the form of securities and through a physical purchase.

Gold in its physical form can be purchased from banks, coin and precious metal dealers as bars or bullion coins. However, the safe keeping of gold at banks usually gives rise to considerable costs which are not incurred when securities are traded.

However, if gold is traded by way of a physically deposited purchase in the form of securities, trading or stock market fees must be paid.

It is possible to invest in the precious metal on the stock exchange or through brokers in the form of gold certificates, gold funds or gold ETFs, without receiving any physical gold.

Another form of investing in gold is Xetra-Gold, a no-par loan, which is denominated in gold holdings. Do you have a piece of gold jewellery and would like to know more information about it?

Gold-Traders has compiled a gold hallmark identification wizard to help decipher the markings that are stamped on your item.

Have a look at your piece of jewellery. These markings will be pretty small, so you'll need a magnifying glass to see them properly! Because of the softness of pure 24k gold, it is usually alloyed with base metals for use in jewelry, altering its hardness and ductility, melting point, color and other properties.

Alloys with lower karat rating , typically 22k, 18k, 14k or 10k, contain higher percentages of copper or other base metals or silver or palladium in the alloy.

The Japanese craft of Mokume-gane exploits the color contrasts between laminated colored gold alloys to produce decorative wood-grain effects.

By , the gold jewelry industry was escalating despite a dip in gold prices. Gold solder is used for joining the components of gold jewelry by high-temperature hard soldering or brazing.

If the work is to be of hallmarking quality, the gold solder alloy must match the fineness purity of the work, and alloy formulas are manufactured to color-match yellow and white gold.

Gold solder is usually made in at least three melting-point ranges referred to as Easy, Medium and Hard. By using the hard, high-melting point solder first, followed by solders with progressively lower melting points, goldsmiths can assemble complex items with several separate soldered joints.

Gold can also be made into thread and used in embroidery. Though gold is attacked by free chlorine, its good conductivity and general resistance to oxidation and corrosion in other environments including resistance to non-chlorinated acids has led to its widespread industrial use in the electronic era as a thin-layer coating on electrical connectors , thereby ensuring good connection.

For example, gold is used in the connectors of the more expensive electronics cables, such as audio, video and USB cables. The benefit of using gold over other connector metals such as tin in these applications has been debated; gold connectors are often criticized by audio-visual experts as unnecessary for most consumers and seen as simply a marketing ploy.

However, the use of gold in other applications in electronic sliding contacts in highly humid or corrosive atmospheres, and in use for contacts with a very high failure cost certain computers , communications equipment, spacecraft , jet aircraft engines remains very common.

Besides sliding electrical contacts, gold is also used in electrical contacts because of its resistance to corrosion , electrical conductivity , ductility and lack of toxicity.

Fine gold wires are used to connect semiconductor devices to their packages through a process known as wire bonding.

The concentration of free electrons in gold metal is 5. For example, gold electrical wires were used during some of the Manhattan Project 's atomic experiments, but large high-current silver wires were used in the calutron isotope separator magnets in the project.

Metallic and gold compounds have long been used for medicinal purposes. Gold, usually as the metal, is perhaps the most anciently administered medicine apparently by shamanic practitioners [] and known to Dioscorides.

Even some modern esotericists and forms of alternative medicine assign metallic gold a healing power. In the 19th century gold had a reputation as a "nervine", a therapy for nervous disorders.

Depression , epilepsy , migraine , and glandular problems such as amenorrhea and impotence were treated, and most notably alcoholism Keeley, The apparent paradox of the actual toxicology of the substance suggests the possibility of serious gaps in the understanding of the action of gold in physiology.

Some gold salts do have anti-inflammatory properties and at present two are still used as pharmaceuticals in the treatment of arthritis and other similar conditions in the US sodium aurothiomalate and auranofin.

These drugs have been explored as a means to help to reduce the pain and swelling of rheumatoid arthritis , and also historically against tuberculosis and some parasites.

Gold alloys are used in restorative dentistry , especially in tooth restorations, such as crowns and permanent bridges.

The gold alloys' slight malleability facilitates the creation of a superior molar mating surface with other teeth and produces results that are generally more satisfactory than those produced by the creation of porcelain crowns.

The use of gold crowns in more prominent teeth such as incisors is favored in some cultures and discouraged in others. Colloidal gold preparations suspensions of gold nanoparticles in water are intensely red- colored , and can be made with tightly controlled particle sizes up to a few tens of nanometers across by reduction of gold chloride with citrate or ascorbate ions.

Colloidal gold is used in research applications in medicine, biology and materials science. The technique of immunogold labeling exploits the ability of the gold particles to adsorb protein molecules onto their surfaces.

Colloidal gold particles coated with specific antibodies can be used as probes for the presence and position of antigens on the surfaces of cells.

Gold, or alloys of gold and palladium , are applied as conductive coating to biological specimens and other non-conducting materials such as plastics and glass to be viewed in a scanning electron microscope.

The coating, which is usually applied by sputtering with an argon plasma , has a triple role in this application. Gold's very high electrical conductivity drains electrical charge to earth, and its very high density provides stopping power for electrons in the electron beam , helping to limit the depth to which the electron beam penetrates the specimen.

This improves definition of the position and topography of the specimen surface and increases the spatial resolution of the image. Gold also produces a high output of secondary electrons when irradiated by an electron beam, and these low-energy electrons are the most commonly used signal source used in the scanning electron microscope.

The isotope gold half-life 2. Pure metallic elemental gold is non-toxic and non-irritating when ingested [] and is sometimes used as a food decoration in the form of gold leaf.

Although the gold ion is toxic, the acceptance of metallic gold as a food additive is due to its relative chemical inertness, and resistance to being corroded or transformed into soluble salts gold compounds by any known chemical process which would be encountered in the human body.

Soluble compounds gold salts such as gold chloride are toxic to the liver and kidneys. Common cyanide salts of gold such as potassium gold cyanide, used in gold electroplating , are toxic by virtue of both their cyanide and gold content.

There are rare cases of lethal gold poisoning from potassium gold cyanide. Gold metal was voted Allergen of the Year in by the American Contact Dermatitis Society; gold contact allergies affect mostly women.

A sample of the fungus Aspergillus niger was found growing from gold mining solution; and was found to contain cyano metal complexes, such as gold, silver, copper, iron and zinc.

Answer: Not sure where you read that. It is gold parts per parts of the alloy. This gold jewelry marking does not indicate how the ring was crafted.

Question: My gold rope chain has 14k on one side and a heart with initials "O. Is it real? Answer: The intials have nothing to do with the purity.

The 14K gold stamp means the necklace is real 14 karat gold. Answer: Gold is a weak metal and bends easily. So the strongest gold jewelry would be the lowest purity, like 8KT gold.

But it doesn't look much like gold. Answer: "Ag" is the symbol for silver on on the periodic table of elements. So the necklace is sterling silver and was made in Italy.

What about the "L" mark? The "L" marking could mean anything. Question: I have a Cartier love bracelet I got used. It has a slightly tarnished look to it but has a stamp.
