Gold rings aren't pure gold, or they'd bend very easily.

Sure. But they'd never ever corrode. ;-)

Not sure on your maths there.

A cube 1.1mm in a side has a volume of about 0.001331 cubic cm. A bit 
over one thousandth of a cubic cm.

A cube 1.17cm (11.7mm) on a side would have a volume of approximately 
1.6 cubic cm.  And that is about right for an ounce of gold.

Oh, OK. I misread the unit on the printout. Well that's a rather larger 
lump of gold then. ;-)

Wolfram was clueless, but wikipedia says it's 91.x% gold, so weighs 1.09 oz.

If you're making decorative items, this is a benefit.

     You can't get better than 24 carat. Well, in fact, you can't get 24ct, 
it will always be 999.999 fine gold.

As I said later, I looked it up and it's about 91% gold. I realized after 
I'd written this that bullion *coin* probably isn't close to 24k. :-)

 Ah right, well, I didn't read every post in this thread, but it reminds me 
of a guy that came to one of my old places of work to sell 150 full gold 
sovereigns. He had them in plastic tubes that held ten each, so I picked 
them up and was surprised by the weight.
