Where Does Gold Come From? | Colour: The Spectrum of Science | Earth Science

Where does gold come from before it makes its way into jewelry? Helen Czerski explores the methods old prospectors used to find gold.

Just 15 colours tell the whole story of the Earth, Life and scientific discovery. Helen Czerski takes us on a journey across the planet and through deep history to track them down and discover the chemistry, biology and physics of colour.

Here at BBC Earth Science we answer all your curious questions about science in the world around you. If there’s a question you have that we haven’t yet answered or an experiment you’d like us to try let us know in the comments on any of our videos and it could be answered by one of our Earth Science experts.

Every time I look at my gold chain I think of the history it caries. I'm wearing something that's billions of years old. Traveled from light years away, and is older then all life as we know...

Where exactly was that river again????

She would match perfectly with Brian Cox

I find it Ridiculous how you never mentioned where Gold comes in the first place. *Super Novas, * _you're welcome_

Gold is a different shade in different areas of the Earth. If you want to know the real origin of gold it is on another channel.

she found the perfect place to earh her feet, thats smart thinking !

[shawnkovac]

that's so cool! i had the opportunity once to pan for gold. it uses those principles. it's fascinating! Helen, you are fascinating too! and brilliant! thanks for being the interesting person you are!!

[StevenJeNova]

Where does Gold come from? Eh..., from merging Neutron stars, most likely?

[williamschnl]

there will be sometime in the future, human says, "back then, gold was a precious metal." just like now, where we say, "back then, salt was precious, it even was used as currency."

I like the host's voice. She seems to be nice :>

[terry]

Wow such science and I'm a clickbait fool 😂

[wormwood]

Ahhh.... finally a good gold digger 😊 ❤️

[carlmanis]

gold is 4 or 5 different medals mix together at the temperatures above gases state under great pressure and slowly cooled. Why do you squirts out of rocks and run in veins.

[Schemez-vhiphopbeatz]

Gold comes from neutron stars colliding... Maybe in super novas too

[fidelcatsro]

wow 1 gram of gold for every 1000, 000, 000 grams of soil!!

[marklestergamayon]

Some says it from space were asteroids and comets were exploded then come to earth? But some learning says its a mineral from this world called earth

[geetugupta]

3:02 I'm holding a piece of pure gold😊
Me:🤣🤣🤣😆😆😅 Sure you are!!
Also, all gangsters:Where is this place👀🤑!?

[jamesraymond]

Gold didn't originate in the solar system as implied. Not even in the Milky Way galaxy. That's because the stars in the Milky Way have very low amounts of heavy metals. Earth's gold may have come from a distant galaxy following a collision of neutron stars.

Why fill it with your mind boggling millions of years

Gold is biology…. It is remain of giants of old
