Gold

GOLD HISTORY

Over 80% of the world's gold was formed by earthquakes—they pull rocks apart so quickly that the fluids inside them vaporize, leaving gold.

Archaeologists have found that the earliest human interest in gold came with Palaeolithic Man, who lived around 40,000BC and hoarded nuggets of natural gold.

The people of Lydia (now western Turkey) introduced gold money around 700BC.

The Ancient Greeks thought that gold was a dense combination of water and sunlight.

24-carat gold and the measurement of purity in divisions of 24 have their origins in the 4th Century when the Romans minted a new gold coin that was the same weight as 24 smaller coins called siliqua.

Before the Spanish conquest of South America, the Incas of Peru used gold for everyday objects such as nails, combs and dishes.

The explorer Martin Frobisher discovered in 1576 what he thought was gold in the Arctic- but it turned out to be a useless mineral called “Fool’s Gold”.

The idea of linking the value of money to the price of gold came in with the US congress. The first gold prices were fixed by Congress on April 2, 1792, at $19.39 an ounce. It’s “Gold Standard” has been maintained despite fluctuations in gold's value, ever since.


The "Welcome Stranger" was the name given to the largest gold nugget ever found in the world, with a calculated refined weight of 2,315 oz (72kg). It was discovered by John Deason and Richard Oates at Moliagul, Victoria, Australia on February 5, 1869 about 9 miles north-west of Dunolly. The nugget was found only three centimeters below the surface, near a root of a tree on a slope leading to what was then known as Bulldog Gully.

Gold prices on the New York Mercantile Exchange hit $1,000 per ounce for the first time on March 13, 2008.

100,000 tons of gold has been mined since 1500 - just enough to fill two Olympic size swimming pools.
