Hehehe, I know this is kinda OT, but I do
possess one of these "rocks" @ home
It is nicely put in a Glass cube under Vacuum (My Dad got it when he was living in Rwanda, back in the 60's), and is loosing it's "shine" somewhere in the basement... anyone wanna buy it ?
I'll try to mae a pic of it & post it here, since you all seem to be interested in Elephant Doodoo...
