How is gold formed in nature?

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.

In more recent times, jewellers no longer create jewellery with osmium alone, but replace the traditional diamond, which is not as easy to work with, with osmium.

Why is osmium so expensive?

Osmium tetroxide is expensive because osmium is a rare element. Osmium is one of the rarest elements in the Earth's crust. Osmium is obtained as a by-product from nickel and copper processing. The US production of Os is probably only about 75 kg/year.
