Hello! I'm doing a paper on India and I would like to know if you or anyone can give me information and tell me, what is the most expensive rock on earth. If you can't help me can you direct me to someone who could. thanks
isnt it a real big diamond?
It must surely be the samples of Moon rocks bought back during the various missions by the U.S.A. The true cost of these few pounds of material must run into billions of dollars, taking into account the whole space program before these extra-terrestrial rocks were brought to earth.
