Maybe it was a bad choice of word.
I was thinking of how few uses it has. Gold is a good conductor, is very malleable and doesn't corrode easily; it makes sense that it's expensive. Diamond could be replaced by glass in a ring and not many people (other than your bank manager) would be any the wiser.

The price is kept artificially high though limited release.
A guy I worked with in the jewelry trade went to the russian diamond stores years ago.
There were shipping containers full of uncut stones.
A lot of the demand against blood diamonds is them stopping unregulated supply lowering the price.
