Gold facts/information Quote then add your facts

A cubic centimetre of gold weight 19.3 grams

A cubic inch weight is 10 ounces

Gold is Au and silver is Ag

Atomic n° of gold is 79 (Au79)

Silver is a better conductor of heat and electricity than gold but gold does not oxidize.

Gold is soft, dense, malleable, ductile

Gold is malleable enough for just 1 gram to be hammered into a sheet 1 square meter in size.

The melting point of Gold is 1,064.43°C (1,947.97°F).

100% of gold found naturally is isotope Au-197.

 187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons)

 gold is “diamagnetic”, meaning that it can be repelled by a magnetic field, but cannot form a permanent magnet.

United States. Tonnes: 8,133.5 in 2020

China. Tonnes: 1,948.3

The first Gold coins appeared around 700 BC.

An ounce  can be beaten out to 187 square feet (about 17 square metres)

 1870s until World War I the gold standard was the basis for the world’s currencies. 

Gold was the international monetary system, it came to an end by the 1970s

Gold occurs mostly in the native state, except with telluriumselenium, and bismuth

Between about 4-27 micrograms per cubic meter: Micrograms of gold in 1 cubic meter of seawater.

5,600,000,000,000 - 37,800,000,000,000:  Total grams of gold in all seawater on Earth

I think the above is what happened to this one.  Looks like a 3 oz'er to only come in at 1.3 ozt.  Still a momentous recovery for that area and the person who dug it.

Find a profitable way to concentrate that and get mighty rich! 🤑

Let's take the lower bound of GotAU's calculation since the 4-27 mircrograms of gold per cubic meter of seawater appears to be a range of measurements and we don't know the world average -- somewhere in that range presumably.  Now, divide that by the amount of gold recovered to date (estimate in Geof's post) and we find that there is at least 30 times as much gold in the Earth's oceans as has ever been recovered (from the land).

However, that's still a drop in the bucket compared to what is still deep in the earth -- at least 4x10^18 g, 4 followed by 18 zeroes or four quintillion grams.  That's 100,000 to a million times what GotAU's calculation says is in the oceans.  (Calculated based on the mass of the earth's mantle times the [conservative] fraction of gold in the earth's crust; thus I'm assuming mantle and crust have similar compositions which might not be true.)

It's a bit surprising to me that the Netherlands and Iran are ranked that high. I would have thought Canada, Mexico, Brazil, Australia,and South Africa would be higher.

Check this site out Gold In the world visualized

That page (and site) have fantastic graphics.  A few clarifications:

1) the gold depicted in the photo Steve posted is what governments hold.  According a later graphic on that page it's only between 17% an 18% of all the gold in possession.

2a) although it's true that in 1933 it was made illegal to own gold bullion (kept in the USA, see below) and each person was limited to $100 face value in gold coins, the possession of gold in jewelry form was allowed, and jewelers were excepted (presumably within limits) on owning bullion for the purposes of making jewelry.

2b) a loophole(?) was stepped through by owning gold kept offshore (mostly housed in Europe, especially Switzerland).  Recently much of that gold which was in the form of USA coins (especially $20 gold pieces) has been returning to the USA and is being sold to numismatic collectors.  If you've ever watched Rick Tomaska's cable TV show (on Rare Collectibles TV) you'll have seen many presentations where he discusses acquiring some of that and subsequently sells cherry picked high grade specimens to viewers.

2c) the USA government kept close records on how much gold (in the form of coins) they melted, broken down by denomination.  A graphic shown occasionally on the above mentioned show indicates that less than half of any single denomination ever minted by USA was melted, before and after the 1933 buyback.  (I think they melted all coins in their possession, including recovered from the so-called 'confiscation' buyback.)  So there is still quite a bit out there, somewhere....

A big question for detectorists is "how much has been lost/hidden awaiting our detectors to sound off over them?"  (That's not explcitly shown in the graphics Steve linked to.  😁)

So, that four quintillion grams of gold on Earth, divided by 7.7 billion people means that our shares are over 518 million grams each?!  Well come’on, lets go!! 🤪

We're gonna need more than plastic scoops to reach it.  (Sorry, Gerry, if I just killed a mad rush on sales.)  Even these Russians only got down a bit over 12 km of the 2900 km thickness (crust + mantle) and it took them 19 years to do that!
