From Who’s Got All The Gold, And Who’s Mining It:
All Gold Ever Mined – The total amount of gold ever mined is estimated to be worth around US$5 trillion.
How Gold is Used – You might have though (like me) that most of the gold in the world stored in bank vaults and lock-boxes? Actually, 78 % of the worlds’ gold is made into jewelery. Other industries, mostly electronics, medical, and dental, require about 12%. The remaining 10% of the yearly gold supply is used in financial transactions.

“[Gold] gets dug out of the ground in Africa, or someplace. Then we melt it down, dig another hole, bury it again and pay people to stand around guarding it. It has no utility. Anyone watching from Mars would be scratching their head.”
