How can u tell if gold is real?
To perform this test to check if gold is real, make a light, tiny scratch on the item using a small nail file. Choose a spot that is not noticeable if possible. Use a dropper to apply a small drop of nitric acid to the scratch. If there is no reaction, then the piece is probably made from real gold.

Does gold float in water?
Gold is hydrophobic: it repels water. Because of this, even if the piece of gold is first completely submerged, if it gets near the surface it will throw off the water above it and float. … Since most placer gold is flat and thin, its weight is small relative to its circumference so it will usually float.

Does pyrite float in water?
Since mineral matter and pyrite (Fool's gold) are more dense than salt water, they fall to the bottom of the solution. Less dense particles (clean coal) will float. The suspended particles are minerals lighter than pyrite, but heavier than clean coal.
How is gold formed?
Magma penetrates into solid rock walls carrying the gold within it. When the magma cools it leaves new layers of rock and minerals, including gold, inside of the existing rock. Placer gold is formed from already existing lode and intrusive gold deposits. Placer gold is caused by the eroding effect of water upon rock.
What good is pyrite?
