Send any "inert" object....
for the low price of $2,500.00 per gram.
Note the disclaimer: "due to the velocity at which the 2001 TrailBlazerTM spacecraft will impact at the end of the mission, as well as the unknown nature of the lunar surface at the point of impact, no guarantee can be made as to the state of the payload following its arrival on the surface."
Don't send up the good china. ;-)
