The rock that gold is found in is Quartz rock.

When quartz is found in gold bearing areas it's also possible that gold will be found as well.

A strong magnet will attract gold but will also retract it as well as gold is diamagnetic and paramagnetic that means both will cancel each other out and become weak.

Pyrite is most often mistaken for gold.

Pyrite is called “Fool's Gold” because it resembles gold to the untrained eye.

While pyrite has a brass-yellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does.

To test gold with a lighter you heat the gold using the lighter and then watch the gold closely for any changes in color.

Fake gold will get darker, while pure gold will do the opposite: it will get brighter the hotter it gets.

The brighter your jewelry gets, you can rest assured you have real gold.

You can also check if gold is real by using a magnet and or scratching the gold with a hard object such as ceramic and if the gold is real then it will leave a golden or yellowish streak.

However if the gold is fake and you scratch it then it will leave a dark streak.

Also a magnet will not stick to real gold and if you use a magnet on the gold and it sticks then it's fake gold.

Real and pure gold will not stick to a magnet.

If the gold sticks to a magnet then it is not real gold and is most likely gold that is made of steel with a gold coating.

Fake gold will stick to a magnet and real gold will not stick to a magnet.

Gold is a chemical element with the symbol Au and atomic number 79.

The Gold is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in pure form. Chemically, gold is a transition metal and a group 11 element.

It is one of the least reactive chemical elements and is solid under standard conditions.

The price of gold is based on the spot price of the metal, which changes daily.

The current market demand and supply determine the spot price.

Gold is usually found embedded in quartz veins, or placer stream gravel.

It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia and Canada.

The largest known deposits of gold appear on two continents, Africa and India.

In these two regions, South Africa has the largest concentration of gold with the town of Johannesburg being built over the worlds largest gold deposit.

Currently the top gold mining state of the US, Nevada is home to three of the world's top 10 gold mines and seven of the top 10 US sites.

Nevada's Goldstrike is the top gold mine in the US, followed by the Cortez and Carlin Gold Mines, with all three located in north-central Nevada.

Australia and Russia hold a large share of the world's gold mine reserves, accounting for 8,400 metric tons and 6,800 metric tons, respectively.

The oceans contain around 20 million tons of dissolved gold.

However, this means there is only about one gram of gold for every 110 million tons of ocean water.

Many gold deposits exist deep within the sea floor, and some deposits can often be trapped underneath rock as far down as 35,000 feet.
