uses of gold in medicine

Gold  has been used in medicine since the ancient times. It  has been in use for the treatment of rheumatoid arthritis for quite some time. It has been very effective in reducing stiffness as well as the pain.The use of gold for beauty treatments today is no longer a novel idea.Modern medical research has revealed that gold helps to stimulate re-growth of skin cells and fight the degradation of collagen.Gold is also found to have high resistance against bacteria, which makes it very effective in fighting common infections. It has also been helpful in the treatments of cancer.Other applications of gold in medicine include treatment for the following health conditions: rheumatoid arthritis, heart disease, and HIV. Many diseases such as smallpox, measles and skin ulcers were treated and it is also used  in an eye surgery procedure to correct a condition, known as Lagophthalmos, where eyelids cannot be fully closed.Thus, it has a great importance in todays world and is very helful in every sector.

Uses of gold in Monetary exchange

Gold has been widely used throughout the world as a vehicle for monetary exchange, either by issuance and recognition of gold coins or other bare metal quantities, or through gold-convertible paper instruments by establishing gold standards in which the total value of issued money is represented in a store of gold reserves.

However, production has not grown in relation to the world's economies. Today, gold mining output is declining.With the sharp growth of economies , and increasing foreign exchange, the world's gold reserves and their trading market have become a small fraction of all markets and fixed exchange rates of currencies to gold were no longer sustained.
Pure gold is too soft for day-to-day monetary use and is typically hardened by alloying with copper, silver or other base metals. The gold content of alloys is measured in carats (k).
Pure gold is designated as 24k. English gold coins intended for circulation from 1526 into the 1930s were typically a standard 22k alloy called crown gold, for hardness (American gold coins for circulation after 1837 contained the slightly lower amount of 0.900 fine gold, or 21.6 kt).

Uses of gold in Jewelry

Everyone love jewelry because it is very beautiful n precious too .All people love the jewelry which adds more beauty to the people who wear it ,The production of ornamental objects was probably the first use of gold over 6000 years ago. Gold is found in the pure state, is very easy to work and was probably the first metal used by humans. in the modern world jewelry have very high price to talk about the jewelry it is made from the gold which is very  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.Copper is the most commonly used base metal, yielding a redder color. Eighteen-carat gold containing 25% copper is found in antique and Russian jewelry and has a distinct, though not dominant, copper cast, creating rose gold. Fourteen-carat gold-copper alloy is nearly identical in color to certain bronze alloys, and both may be used to produce police and other badges. Blue gold can be made by alloying with iron and purple gold can be made by alloying with aluminium, although rarely done except in specialized jewelry. Blue gold is more brittle and therefore more difficult to work with when making jewelry. Fourteen and eighteen carat gold alloys with silver alone appear greenish-yellow and are referred to as green gold. White gold alloys can be made with palladium or nickel. .Special properties of gold make it perfect for manufacturing jewelry. These include: very high luster; desirable yellow color; tarnish resistance; ability to be drawn into wires, hammered into sheets or cast into shapes. These are all properties of an attractive metal that is easily worked into beautiful objects. Pure gold is too soft to stand up to the stresses applied to many jewelry items.White gold is an alloy of 75% gold, 4% silver, 4% copper and 17% palladium. Other alloys yield pink, green, peach and even black colored metals. Since then most gold used to make jewelry is an alloy of gold with one or more other metals.
The alloys of gold have a lower value per unit of weight than pure gold.In general, high karat jewelry is softer and more resistant to tarnish while low karat jewelry is stronger and less resistant to tarnish.

Uses of gold in Industry

Gold is also important in industry 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, gold solder must match the carat weight of the work, and alloy formulas are manufactured in most industry-standard carat weights 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.

Uses of gold in Electronics

 Gold is highly conductive to electricity, and has been used for electrical wiring in some high-energy applications. 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.
Though gold is attacked by free chlorine, its good conductivity and general resistance to oxidation and corrosion in other environments has led to its widespread industrial use in the electronic era as a thin layer coating electrical connectors of all kinds, 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 is highly debated. Gold connectors are often criticized by audio-visual experts as unnecessary for most consumers and seen as simply a marketing ploy. However, the most important industrial use of gold is in the manufacture of electronics. Solid state electronic devices use very low voltages and currents which are easily interrupted by corrosion or tarnish at the contact points. Gold is the highly efficient conductor that can carry these tiny currents and remain free of corrosion. Electronic components made with gold are highly reliable. Gold is used in connectors, switch and relay contacts, soldered joints, connecting wires and connection strips.
A small amount of gold is used in almost every sophisticated electronic device. This includes: cell phones, calculators, personal digital assistants, global positioning system units and other small electronic devices. Most large electronic appliances such as television sets also contain gold. One challenge with the use of gold in very small quantities in very small devices is loss of the metal from society. A facts nearly one billion cell phones are produced each year and most of them contain about fifty cents worth of gold. Their average lifetime is under two years and very few are currently recycled. Although the amount of gold is small in each device, their enormous numbers translate into a lot of unrecycled gold.

History of silver

From the ancient time it has been known as a precious metal Silver compounds were used to prevent infection Silver has been used for thousands of years for ornaments and utensils, for trade, and as the basis for many monetary systems. Its value as a precious metal was long considered second only to gold. The stability of the Roman currency relied to a high degree on the supply of silver bullion, which Roman miners produced on a scale unparalleled before the discovery of the New World. Reaching a peak production of 200 ft per year, an estimated silver stock of 10,000 t circulated in the Roman economy in the middle of the second century AD, five to ten times larger than the combined amount of silver available to medieval Europe  when it was used for several purposes, such as to  used in food coloring disinfect water and food during storage, and also for the treatment of burns and wounds as wound dressing. In the 19th century, sailors on long ocean voyages would put silver coins in barrels of water and wine to keep the liquid potable. Pioneers in America used the same idea as they made their journey from coast to coast. Silver solutions were approved in the 1920s by the US Food and Drug Administration for use as antibacterial agents.

History of gold

Gold artifacts  appear from the 4th millennium BC Although the price of some platinum group metals can be much higher, gold has long been considered the most desirable of precious metals, and its value has been used as the standard for many currencies in history. Gold has been used as a symbol for purity, value, royalty, and particularly roles that combine these properties. Gold as a sign of wealth and prestige .On that imaginary island, gold is so abundant that it is used to make chains for slaves, tableware and lavatory-seats.There is an age-old tradition of biting gold to test its authenticity. Although this is certainly not a professional way of examining gold, the bite test should score the gold because gold is a soft metal, as indicated by its score on the Mohs' scale of mineralhardness. The purer the gold the easier it should be to mark it, 75% of all gold ever produced has been extracted since 1910. It has been estimated that all gold ever refined would form a single cube 20 m.In medieval times, gold was often seen as beneficial for the health, in the belief that something that rare and beautiful could not be anything but healthy. Even some modern esotericists and forms of alternative medicine assign metallic gold a healing power. The first use of gold as money occurred around 700 B.C. Their symbol for gold was the circle with a point at its center , which was also the symbol and the ancient Chinese character for the Sun. For modern creation of artificial gold by neutron capture,During the 19 th century, gold rushes occurred whenever large gold deposits were discovered. The first documented discovery of gold in the United States was at the Reed Gold Mine. The first major gold strike in the United States occurred in a small north Georgia town called Dahlonega. Because of its historically high value, much of the gold mined throughout history is still in circulation in one form or another.

How to Invest in Gold or Silver

Investing in precious metals such as gold and silver can be done by purchasing items which are made of them. Some of which include jewelry, coins, bars or bullions. These can be purchased in legitimate stores and over the internet.investing in gold for financial survival has become a necessity as the entire world. Making matters worse, the United States is in the midst of a spectacle of deficit spending like the world has neverseen.Although investing in gold is not yet mainstream, investing in gold has become the safe haven for many investors who fear that the creation of fiat dollars will not stop until the dollar is worthless.

In precious metals bull markets, investing in silver instead of investing in gold provides greater percentage gains because silver outperforms gold in precious metals bull markets.Adding to the appeal of silver to investors is the huge and growing industrial demand for silver, which means that investing in silver could be profitable for years to come.

But, the primary reason investing in silver instead of gold results in greater profits is that silver is "the poor man's gold." When the masses come to this market, they will buy silver, and in the aggregate the masses have more money than the wealthy.Gold or silver investment has great potential. These do not depreciate in value. They have been proven to be more effective in trade over the past 6,000 years.

Why Invest in Gold or Silver ?

In this modern age Investing in gold and silver has many benefits.its the precious metal which is very limited so the demand in high n the production is low so the price will surely increase thus to invest in it is a safe task .  Another benefit is the wide range of industries wherewith these items are applied upon. Some of which includes monetary coinage, jewelry, arts, computers, electronics, space travel, medicine, dentistry, among many others.The precious metals like gold and silver are the backbone of an economy that depends on paper and credit as currency. Because of this, investing in gold stocks is absolutely a good idea for any investor.This may be attributed to the rising demand for these metals and the scarcity of supply attached to them.When it comes to precious metals, gold is without a doubt the most popular choice for investors. Gold and silver investments have been noted to remain constant or to even increase in value over trades and exchanges. When most currencies have fallen during the economic turmoil gold, silver, and other precious metals did not depreciate in value. In fact, they seem to be even increasing in value. If there are times that it would decrease, it is hardly ever noticeable. Besides, its value is based on the ups and downs of the economy and the stock market.
Investors purchase gold is as a way to hedge against the economy. If the dollar drops or the economy crashes, gold is going to be one of the few investments that weathers the storm, so to speak.   There are sources all over the world for important metals and minerals but the danger of mining such deposits and the costs involved makes them more expensive and valuable. The costs cover manpower, equipments, storage, and conversion into materials which can be used.

why gold is expensive ?

From gold we can make ornaments ,it wont rust or spoil by its own like other metals . it's no longer tied to most world currencies, and with the economy being in such bad shape, there's a lot of perceived weakness in the world's fiat currencies (just a fancy name for money that has nothing backing it). So people are flocking to gold to hedge their bets against shaky currencies. Gold is perceived to be more valuable than fiat currency because of its past reputation as a store of wealth, plus there's only so much of it to go around, whereas governments can just turn on their printing presses and make more money. They couldn't do that when currencies were backed by gold, and every time they do it, currency becomes more and more devalued. Meanwhile, nobody's making more gold.It's rare, it's hard to extract from the ground, it doesn't tarnish, and it's been a symbol of wealth for centuries .It's getting expensive now because it's no longer tied to most world currencies, and with the economy being in such bad shape, there's a lot of perceived weakness in the world's fiat currencies .

Gold Demand Climbs 11% as Investment Drives Prices to Record, Council Says

Gold demand rose 11 percent in the first quarter as China helped boost investment and jewelry usage, while demand will remain "firm" throughout this year,
Global demand gained to 981.3 metric tons in the quarter, compared with 881 tons a year earlier, the London-based industry . China's consumption surged 47 percent in the quarter and may double before 2020 as the growing population's wealth increases and near-term concerns about faster inflation spur investment, the council predicts.
Consumers in China and India "continue to view jewelry not just only as an adornment, but as a good investment.

In the history of gold "Inflation pressure is still an ongoing issue. These concerns are not going away." Prices averaged $1,387.67 in the first quarter, up 25 percent from a year earlier and 1.3 percent more than the fourth quarter.Central banks are adding to their reserves for the first time in a generation, helping prices extend a 10-year rally, the longest run of gains in at least nine decades.

Central bank and government institution purchases doubled to 129.3 tons in the first quarter, exceeding the amount bought in the first three quarters of last year, the council said. Countries will remain net buyers this year, it said.
Total supply declined 4.4 percent to 872.2 tons in the first quarter from a year earlier as central banks purchased the metal and as scrapping fell 6 percent to 347.5 tons, the council said. Mine output rose 7 percent to 663.9 tons.

China, India to boost gold demand in 2011, says WGC

Gold has been one of mankind's most revered substances since the beginning of time.
"High levels of investment demand across the world, strong demand in India and China, the continued strength of the technology sector together with central bank purchasing demonstrates gold's diverse demand drivers.


"These include: continued uncertainty over the US economy and the dollar, ongoing European sovereign debt concerns, global inflationary pressures and continued tensions in the Middle East and North Africa.At the same time, the WGC predicted that more central banks would buy gold as they seek to diversify reserves into assets that are deemed to be less risky.The precious metal scored a series of record peaks throughout the first three months of 2011 "Sustained momentum in Chinese and Indian jewellery demand will underpin growth in the jewellery sector throughout 2011


However, the metal has since tailed off slightly, amid a wider commodities sell-off, and it stood at US$1,489.10
The legends and myths surrounding gold are legendary and for many ancient civilizations, only the most powerful were permitted to bathe in gold's stunning rays. The pharaohs wore multiple gold necklaces and gold bracelets. In India, royal families would layer on gold earrings, gold pendants and gold bangles and in Europe, gold rings set with diamonds and precious gems were the aristocrats' accessories of choice.

Reason to buy silver

I’m convinced that silver is a better buy than ever before. Here are detailed reasons why I believe that is the case.This is a much better time to buy than when prices have already climbed and many are buying just because prices are rising. At those times the risk of a sharp sell-off is high. Now the risk of a prolonged price decline is much lower. There is no bullish “fever” where uninformed investors are driven to buy silver because of a sharply rising price. That will happen, but it’s not true now. While silver is still above the price lows of last fall and higher than year-end prices, the recent price action is nothing to write home about. The price has been below most of the important moving averages, causing silver to be “oversold.” for decades the world’s largest stockpiles of silver were the COMEX warehouse inventories. These COMEX inventories were considered mostly commercial in nature with some portion being held for investment purposes.
Now, the combined inventories in the ETFs and other investment vehicles tower over the holdings in the COMEX by almost 4 to 1. (Over 400 million ounces in the ETFs compared to 120 million oz in COMEX inventories). Given the long-term nature of ETF investment holdings, this massive and historic shift in inventory composition means much less silver is now available to the market. This will exert a strong upward influence on price. Importantly, there has been practically no buying of silver on a leveraged or margin basis. It’s mostly been cash on the barrel. These strong silver buyers will wait for significantly higher prices before selling.Silver is dirt cheap relative to gold. While there is less above ground silver than gold, silver’s price has rarely been this low compared to gold.
 At precisely the same time that prices have declined so sharply,. The manipulation that explains why silver is so cheap cannot exist in a bona fide physical shortage. If the price stays low, growing numbers of investors buy real silver. That makes it harder for the manipulators to keep the price contained with paper derivatives.

Reason to buy gold

Buying gold is the safe property in future which price will not decrease n gonna be shortage ornament today the price of gold is increasing so fast day by day its creating a new record. Whether the economy is up or down and whether unemployment is high or low... the billionaires of the world always seem two steps ahead of EVERYONE ELSE.
In fact, Forbes recently reported that over the past year alone, the richest people in the world are now $1 trillion richer! its beter to buy a gold because supply of gold is very minimum n the demand for gold is so very high so the cost of gold is expensive n will be benefited.Due to financeal crisis it will worsen for a while which will cause ahuge increase in the base monetary supply.it’s usually a decision made taking the positives and negatives into consideration. Perhaps more important would be considering how much of your portfolio you plan to allocate to gold and how much maximum loss you are willing to take.

The gold and silver ratio

It is the gold price divided by the silver price, & shows how many ounces of silver it takes to buy one ounce of gold. The Ratio shows us the Primary (20 year) Trend of gold's value against silver. When the Ratio's trend is dropping, silver is gaining value against gold. This trend targets a gold/silver ratio of 16 ounces of silver to one of gold within the next 5 - 10 years. That implies that silver will massively, vastly outperform gold before this bull market ends. When both metals are rallying, the ratio often (but not always) drops, confirming the rally.
