A few of the tektites gathered through time -"out of this world" remnants of meteorites zipping in and around earth orbit, sometimes surviving the intense heat... presumably from the asteroid feild between Earth and Mars. The lighter is to show scale. The most recent find (the.largest in this group) has what seems like (Au) metal. Extremey difficult to date as new element Lutetium (Lu) is not made in commercial volume which makes it rare. Zeiss should incorporate this in optics, as it has reflective and diffraction properties aside from as above. I have yet to come across a micro diamond meteorite, It shall take perseverance and patience. No space cadets, preferably. :)
