I would have to say weapons grade fissile materials like Uranium and plutonium (which is actually made in breeder reactors)

The value of stones depends on their rarity and esthetical value, not so much on their age. \nSecondly not all stones are as old as the earth. The earth's continental crust is continuasly renewed. New crust forms at mid ocean rifs and wells up in vulcanoes. And crust disappears when one continent al slab slips under another.

Quartz is the mineral that has the best combination of durability and abundance, so much sand is quartz.  It is hard and common, so it must be a typical component of cement.

Iron. \n\nThat 46% figure for oxygen is not correct because it is only for the earth's crust. It does not include the mantle or the core. \n\nFor the entire planet iron makes up 35% of the mass of the planet and oxygen is only 30%. Silicon is 15%, magnesium 13%, and everything else is 7%. \n\nMy source is the USGS (which also cites the 46% oxygen for crust):\nhttp://pasadena.wr.usgs.gov/office/ganderson/es10/lectures/lecture04/lecture04.html

MAKE a diamond?  What are you, Superman?\n\nThe reason diamonds are so expensive is because they cannot be made easily.  The amount of energy required to make a tiny little diamond far exceeds the potential value of the diamond.  That's why you don't see anyone making them.\n\nAt this point in our technological advancement, we have the ability to make nearly everything.  But it's usually not a question of "Can we do it?" but "What's the chepeast way to get it?"  Right now it's cheaper to find diamonds in the earth than it is to make them.

According to the Forbes 2005 World Billionare List, Bill Gates is the richest man in the world, with a personal worth of $ 46.5 Billion. \n\nNow that is a lot of money.

I would say Monaco and Zimbabwe as the poorest. Monaco is the richest for sure per capita.
