Those Carbonado's are cool. Any chance they were formed in space and some
could show signs of entry that might resemble at least the texture of
crust. If the shape and texture was there I can see why it would look like
fusion crust as they are already black and glassy looking.

There is a big difference to a meteorite collector if they are only
impactacites or (drum roll) diamond meteorites!!!

A carbonado with fusion crust? My skepticism meter is pegged. If true it
would be of extraordinary scientific interest, but the problem is that
diamond doesn?t melt. It evaporates. Silicates are content to form what
is
basically a liquid silicon oxide, but carbon oxides (CO, CO2) are gases,
not
liquids. Diamond doesn?t flow &shy; it goes poof.

I looked at those pictures, and there are little spallation flakes on one
side that remind me an awful lot of a carbonate rock.

Caveat emptor.
