Hello, Zirconium I hear is even more valuable than Rhodium, but so far I have not found a price for it anywhere. Charles F. Radley 06:55, 9 January 2007 (PST)
I havent found current figures, but at estimate can probably be made from these statistics.

I made some revisions, and added a few links so people can see where I got the data from. I also added aluminum and nickel, aluminum because it can be easily made from lunar resources (although it's not valuable), and nickel because it is available from nickel-iron asteroids, and arguably may be easy to refine from lunar regolith by magnetic separation. The current price for 3He seemed to be slightly high at 1.5 million dollars per kilogram. It can be purchased from Spectra specialty gasses in 5 liter quantities for $825. At a density of 0.14 g/l at STP, this comes out a little closer to 1.2 million dollars per kilogram, so I corrected this down. --Geoff
