Gold Symbolism. This wiki. My question is about a number on the top cover , side. What does that stand for. There is no other serial number to be found which makes me guess it may have been made in the 30's.
I can not find anyting on the number paert of the stamp but the ADI i found it stands for Amsterdam Diamond is the name of the Danish company from where the sterling silver originated what does the k stand for?
What does made in Italy mean on stamped 10k diamond cut crab link? Looks real but the made in Italy makes me think of silver.
I have a gold tennis bracelet and the only marking on it is the letter "B" on the inside of the clasp. Can anyone tell me what that means?
I have a bangle bracelet with the marking A. Its an antique and it may have come from Europe. What does it mean,. Stone was tested it is a high end real diamond ring.

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! Note : The following gold hallmarking identification wizard is supplied without warranty.
Whilst every effort has been made to ensure its accuracy, we offer no guarantees. Because of its properties, gold is also one of the most important industrial raw materials.
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. Common colored gold alloys include the distinctive eighteen-karat rose gold created by the addition of copper.
Alloys containing palladium or nickel are also important in commercial jewelry as these produce white gold alloys.
Fourteen-karat gold-copper alloy is nearly identical in color to certain bronze alloys, and both may be used to produce police and other badges.
Fourteen- and eighteen-karat gold alloys with silver alone appear greenish-yellow and are referred to as green gold. Blue gold can be made by alloying with iron , and purple gold can be made by alloying with aluminium.
Less commonly, addition of manganese , indium , and other elements can produce more unusual colors of gold for various applications. Colloidal gold , used by electron-microscopists, is red if the particles are small; larger particles of colloidal gold are blue.
Gold has only one stable isotope , Au , which is also its only naturally occurring isotope, so gold is both a mononuclidic and monoisotopic element.
Thirty-six radioisotopes have been synthesized, ranging in atomic mass from to The most stable of these is Au with a half-life of At least 32 nuclear isomers have also been characterized, ranging in atomic mass from to Gold's most stable isomer is m2 Au with a half-life of 2.
No other isomer or isotope of gold has three decay paths. The production of gold from a more common element, such as lead , has long been a subject of human inquiry, and the ancient and medieval discipline of alchemy often focused on it; however, the transmutation of the chemical elements did not become possible until the understanding of nuclear physics in the 20th century.
The first synthesis of gold was conducted by Japanese physicist Hantaro Nagaoka , who synthesized gold from mercury in by neutron bombardment.
Gold can currently be manufactured in a nuclear reactor by irradiation either of platinum or mercury. Only the mercury isotope Hg, which occurs with a frequency of 0.
Other mercury isotopes are converted when irradiated with slow neutrons into one or another mercury isotopesomething, some of which beta decay into thallium.
Using fast neutrons , the mercury isotope Hg, which composes 9. This reaction, however, possesses a smaller activation cross-section and is feasible only with un-moderated reactors.
It is also possible to eject several neutrons with very high energy into the other mercury isotopes in order to form Hg.
However, such high-energy neutrons can be produced only by particle accelerators. Although gold is the most noble of the noble metals ,   it still forms many diverse compounds.
Au I , referred to as the aurous ion, is the most common oxidation state with soft ligands such as thioethers , thiolates , and tertiary phosphines.
Au I compounds are typically linear. The binary gold halides , such as AuCl , form zigzag polymeric chains, again featuring linear coordination at Au.
Most drugs based on gold are Au I derivatives. The gold atom centers in Au III complexes, like other d 8 compounds, are typically square planar , with chemical bonds that have both covalent and ionic character.
Some free halogens react with gold. 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. The earliest recorded metal employed by humans appears to be gold, which can be found free or " native ".
Small amounts of natural gold have been found in Spanish caves used during the late Paleolithic period, c.
The oldest known map of a gold mine was drawn in the 19th Dynasty of Ancient Egypt — BC , whereas the first written reference to gold was recorded in the 12th Dynasty around BC.
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.
