One of the wise men gave gold as a gift to Jesus when he was born. In Communist propaganda, the golden pocket watch and its fastening golden chain were the characteristic accessories of the class enemy, the bourgeois and the industrial tycoons.
Gold Symbolism. Yet gold jewelry can be white or silver, red or rose, and green or lime instead. As you can guess from the markings on gold jewelry, there is more than one gold variety.
I'm referring to the purity only, not the color or style. Different varieties of gold jewelry contain a higher or lower percentage of gold, and there are a few standard varieties.
The purity is expressed in karats or fineness. Pure gold is 24 karats and. So the various fine gold markings, or stamps, tell you the purity of each jewelry item.
More karats the number before the "K" or a higher number means higher gold content. It's "karats", not "carrots!
The term, karat, pertains to gold, and so does karatage confusingly spelled caratage in the UK. In the US, karats are not the same as carats.
A carat is a unit of measurement for gemstones. So most ladies would be thrilled to wear a 1-carat ring diamond, of course.
However, she would sneer if her beau proposed to her with a 1-karat ring, if there were such a thing, because it would be completely worthless. Then he would reply, with a quizzical expression, "I must have misunderstood your request, sweetheart.
Okay, back to gold markings. Look at the table below. It displays all common gold jewelry markings, along with their meanings.
So for each gold variety, it lists the fineness and karatage markings; any piece of jewelry will only be stamped with one or the other.
Then it shows you what percentage of gold each variety of jewelry contains. The chart shows that both and mean karat gold. The USA allows gold jewelry to be under karat, slightly.
In other words, it can be marked 10K when it's only 9. So the higher number marking in these three cases means that it's a higher quality gold, and not under karated.
Most fine gold jewelry is clearly marked or stamped. In which case it will display one of the markings discussed here.
Some jewelry is marked with something else, instead of, or in addition to, those mentioned above. Some other markings mean a jewelry item is not fine karat gold.
In that case, it's either plated or filled gold, or it's costume plain old jewelry—not real gold. See my other guide to find out more about the different kinds of gold plated jewelry, including their markings.
Vermeil, pronounced "ver-may," is gold-plated sterling silver. The is a reference to sterling silver, which is Some other markings convey details about the jewelry's origin.
It may signify who made it, or where it was made, or something similar. In these cases, a logo stands for a manufacturer, and a letter may actually stand for the year of production.
Google is your best chance at finding information about these kinds of unusual jewelry markings. As stated, this article doesn't cover hundreds of other obscure markings that you might find on gold and silver jewelry and other precious metal items.
However, we've covered the basics about gold jewelry markings here. So you should be able to look at the stamp on your gold ring, necklace, bracelet, or earrings and understand what those letters and numbers mean.
If, for example, your gold necklace is marked as or 14K, you know that means 14 Karat gold. Sometimes, that mark may be followed by other letters and numbers.
However, those won't have any bearing on the actual gold content, and their meaning is simply a matter of curiosity.
The item's purity has already been established by the first marking. Answer: Au is the symbol for gold on the periodic table, and means the jewelry is 18 karat gold.
So this stamp is just another way of indicating that the jewelry is 18K gold. Question: I have a gold chain. The only marking on it is "JH.
Answer: Most likely, the absence of an actual gold markings means that it simply isn't gold. Answer: Au is the symbol for gold on the periodic table.
So AU just means the piece of jewelry is 18 karat gold. Answer: If that's the only stamp present, the jewelry probably isn't gold.
Otherwise it would be marked with one the the abbreviations above. Answer: The 14K portion of this marking means the ring is probably 14 karat gold.
Answer: I can only guess that a "" marking means a the item is a higher grade of sterling silver, which is usually marked "" The yellow precious metal is easily workable and conducts electricity and heat.
Because of its excellent conductivity, gold is used particularly in the electrical industry. Gold has also been used in dental technology for around years.
However, gold is used most frequently in the jewelry industry. This line of business accounts for around 75 per cent of the gold worked.
Apart from the Antarctic, where mining is not allowed due to international regulations, the precious metal is mined on all continents.
With a market share of 16 per cent, South Africa is the most important producer of gold. Global stocks of gold have continuously increased in recent decades and are currently at their highest level.
Gold does not react with sulfur directly,  but gold III sulfide can be made by passing hydrogen sulfide through a dilute solution of gold III chloride or chlorauric acid.
Gold readily dissolves in mercury at room temperature to form an amalgam , and forms alloys with many other metals at higher temperatures.
These alloys can be produced to modify the hardness and other metallurgical properties, to control melting point or to create exotic colors.
Gold is unaffected by most acids. It does not react with hydrofluoric , hydrochloric , hydrobromic , hydriodic , sulfuric , or nitric acid.
It does react with selenic acid , and is dissolved by aqua regia , a mixture of nitric acid and hydrochloric acid. Gold is similarly unaffected by most bases.
It does not react with aqueous , solid , or molten sodium or potassium hydroxide. It does however, react with sodium or potassium cyanide under alkaline conditions when oxygen is present to form soluble complexes.
Gold ions in solution are readily reduced and precipitated as metal by adding any other metal as the reducing agent.
The added metal is oxidized and dissolves, allowing the gold to be displaced from solution and be recovered as a solid precipitate.
Caesium auride CsAu , for example, crystallizes in the caesium chloride motif;  rubidium, potassium, and tetramethylammonium aurides are also known.
Some gold compounds exhibit aurophilic bonding , which describes the tendency of gold ions to interact at distances that are too long to be a conventional Au—Au bond but shorter than van der Waals bonding.
The interaction is estimated to be comparable in strength to that of a hydrogen bond. Well-defined cluster compounds are numerous. Medicinal applications of gold and its complexes have a long history dating back thousands of years.
Both gold I and gold III compounds have been investigated as possible anti-cancer drugs. Stable complexes can be generated using different types of bi-, tri-, and tetradentate ligand systems, and their efficacy has been demonstrated in vitro and in vivo.
Gold is thought to have been produced in supernova nucleosynthesis , and from the collision of neutron stars ,  and to have been present in the dust from which the Solar System formed.
Traditionally, gold in the universe is thought to have formed by the r-process rapid neutron capture in supernova nucleosynthesis ,  but more recently it has been suggested that gold and other elements heavier than iron may also be produced in quantity by the r-process in the collision of neutron stars.
This amount, along with estimations of the rate of occurrence of these neutron star merger events, suggests that such mergers may produce enough gold to account for most of the abundance of this element in the universe.
Because the Earth was molten when it was formed , almost all of the gold present in the early Earth probably sank into the planetary core.
Therefore, most of the gold that is in the Earth's crust and mantle has in one model thought to have been delivered to Earth later, by asteroid impacts during the Late Heavy Bombardment , about 4 billion years ago.
Gold which is reachable by humans has, in one case, been associated with a particular asteroid impact. The asteroid that formed Vredefort crater 2.
The discovery of the deposit in launched the Witwatersrand Gold Rush. Notwithstanding the impact above, much of the rest of the gold on Earth is thought to have been incorporated into the planet since its very beginning, as planetesimals formed the planet's mantle, early in Earth's creation.
In , an international group of scientists, established that gold "came to the Earth's surface from the deepest regions of our planet",  the mantle , evidenced by their findings at Deseado Massif in the Argentinian Patagonia.
On Earth, gold is found in ores in rock formed from the Precambrian time onward. Electrum's color runs from golden-silvery to silvery, dependent upon the silver content.
The more silver, the lower the specific gravity. Native gold occurs as very small to microscopic particles embedded in rock, often together with quartz or sulfide minerals such as "fool's gold", which is a pyrite.
The metal in a native state is also found in the form of free flakes, grains or larger nuggets  that have been eroded from rocks and end up in alluvial deposits called placer deposits.
Such free gold is always richer at the surface of gold-bearing veins [ clarification needed ] owing to the oxidation of accompanying minerals followed by weathering, and washing of the dust into streams and rivers, where it collects and can be welded by water action to form nuggets.
Gold sometimes occurs combined with tellurium as the minerals calaverite , krennerite , nagyagite , petzite and sylvanite see telluride minerals , and as the rare bismuthide maldonite Au 2 Bi and antimonide aurostibite AuSb 2.
Gold also occurs in rare alloys with copper , lead , and mercury : the minerals auricupride Cu 3 Au , novodneprite AuPb 3 and weishanite Au, Ag 3 Hg 2.
Recent research suggests that microbes can sometimes play an important role in forming gold deposits, transporting and precipitating gold to form grains and nuggets that collect in alluvial deposits.
Another recent study has claimed water in faults vaporizes during an earthquake, depositing gold. When an earthquake strikes, it moves along a fault.
Water often lubricates faults, filling in fractures and jogs. About 10 kilometres 6. During an earthquake, the fault jog suddenly opens wider.
The water inside the void instantly vaporizes, flashing to steam and forcing silica, which forms the mineral quartz, and gold out of the fluids and onto nearby surfaces.
The world's oceans contain gold. At 10 parts per quadrillion the Earth's oceans would hold 15, tonnes of gold. A number of people have claimed to be able to economically recover gold from sea water , but they were either mistaken or acted in an intentional deception.
Prescott Jernegan ran a gold-from-seawater swindle in the United States in the s, as did an English fraudster in the early s. After analysis of 4, water samples yielding an average of 0.

One of the earliest known maps, known as the Turin Papyrus Map , shows the plan of a gold mine in Nubia together with indications of the local geology.
The primitive working methods are described by both Strabo and Diodorus Siculus , and included fire-setting. Large mines were also present across the Red Sea in what is now Saudi Arabia.
Gold is mentioned in the Amarna letters numbered 19  and 26  from around the 14th century BC. Gold is mentioned frequently in the Old Testament , starting with Genesis at Havilah , the story of the golden calf , and many parts of the temple including the Menorah and the golden altar.
In the New Testament , it is included with the gifts of the magi in the first chapters of Matthew. The Book of Revelation describes the city of New Jerusalem as having streets "made of pure gold, clear as crystal".
Exploitation of gold in the south-east corner of the Black Sea is said to date from the time of Midas , and this gold was important in the establishment of what is probably the world's earliest coinage in Lydia around BC.
From the 6th or 5th century BC, the Chu state circulated the Ying Yuan , one kind of square gold coin. In Roman metallurgy , new methods for extracting gold on a large scale were developed by introducing hydraulic mining methods, especially in Hispania from 25 BC onwards and in Dacia from AD onwards.
They also exploited smaller deposits in Britain , such as placer and hard-rock deposits at Dolaucothi. The various methods they used are well described by Pliny the Elder in his encyclopedia Naturalis Historia written towards the end of the first century AD.
During Mansa Musa 's ruler of the Mali Empire from to hajj to Mecca in , he passed through Cairo in July , and was reportedly accompanied by a camel train that included thousands of people and nearly a hundred camels where he gave away so much gold that it depressed the price in Egypt for over a decade, causing high inflation.
Gold was at a high price in Egypt until they came in that year. The mithqal did not go below 25 dirhams and was generally above, but from that time its value fell and it cheapened in price and has remained cheap till now.
The mithqal does not exceed 22 dirhams or less. This has been the state of affairs for about twelve years until this day by reason of the large amount of gold which they brought into Egypt and spent there [ The European exploration of the Americas was fueled in no small part by reports of the gold ornaments displayed in great profusion by Native American peoples, especially in Mesoamerica , Peru , Ecuador and Colombia.
The Aztecs regarded gold as the product of the gods, calling it literally "god excrement" teocuitlatl in Nahuatl , and after Moctezuma II was killed, most of this gold was shipped to Spain.
The concept of El Dorado underwent several transformations, and eventually accounts of the previous myth were also combined with those of a legendary lost city.
El Dorado, was the term used by the Spanish Empire to describe a mythical tribal chief zipa of the Muisca native people in Colombia , who, as an initiation rite, covered himself with gold dust and submerged in Lake Guatavita.
The legends surrounding El Dorado changed over time, as it went from being a man, to a city, to a kingdom, and then finally to an empire. Gold played a role in western culture, as a cause for desire and of corruption, as told in children's fables such as Rumpelstiltskin —where Rumpelstiltskin turns hay into gold for the peasant's daughter in return for her child when she becomes a princess—and the stealing of the hen that lays golden eggs in Jack and the Beanstalk.
The top prize at the Olympic Games and many other sports competitions is the gold medal. Although they never succeeded in this attempt, the alchemists did promote an interest in systematically finding out what can be done with substances, and this laid the foundation for today's chemistry.

Similarly the Wat Phra Kaew emerald Buddhist temple wat in Thailand has ornamental gold-leafed statues and roofs. Some European king and queen's crowns were made of gold, and gold was used for the bridal crown since antiquity.
A Greek burial crown made of gold was found in a grave circa BC. Roman aureus of Hadrian ; — AD; 7. Pre-Columbian pendant with two bat-head worriors who carry spears; 11th—16th century; gold; overall: The symbol Au is from the Latin : aurum , the Latin word for "gold".
Outside chemistry, gold is mentioned in a variety of expressions, most often associated with intrinsic worth. Winners of athletic events and other graded competitions are usually awarded a gold medal.
Many awards such as the Nobel Prize are made from gold as well. Aristotle in his ethics used gold symbolism when referring to what is now known as the golden mean.
Similarly, gold is associated with perfect or divine principles, such as in the case of the golden ratio and the golden rule.
Gold is further associated with the wisdom of aging and fruition. The fiftieth wedding anniversary is golden. A person's most valued or most successful latter years are sometimes considered "golden years".
The height of a civilization is referred to as a golden age. In some forms of Christianity and Judaism , gold has been associated both with holiness and evil.

In Orthodox Christian wedding ceremonies, the wedded couple is adorned with a golden crown though some opt for wreaths, instead during the ceremony, an amalgamation of symbolic rites.
On 24 August , Israeli archaeologists discovered a trove of early Islamic gold coins near the central city of Yavne. Analysis of the extremely rare collection of gold coins indicated that they were from the late 9th century.
Dating to around 1, years back, the gold coins were from the Abbasid Caliphate.
