Steve, and all,
There are in fact terrestrial "black" diamonds. A these are like all the
"normal" diamonds with an octahedral crystal structure.
Just because they are termed "black" does not make them carbonados. In fact
most carbonado diamonds are not black. They can be brown, sandy brown, green,
dark green and gray, and all the way to pitch black.
But what distinguishes them from all normal octahedral crystal black diamonds
is their porous structure, A clear indication that they formed in a very low
pressure environment, such as in space as Dr. Haggarty proposed with regards to
his research.
It is interesting to note the fact that they are found only on the shores of
two continents. And if you put the two land masses of Africa and South
America together the spots coincide.
So that said, just because a diamond is black does not make it a "carbonado."
If one puts a normal octahedral black diamond against a true carbonado, the
difference is very apparent even without magnification.
The question remains. Where did these carbonados come from, if no mechanism
for their formation can be found on earth?

If you ever have the chance to travel to Crater of diamonds state park in
Arkansas they have a nice display of diamonds mined from the volcanic vent to
include black cabanado diamonds. If they are meteoric ,the meteorite hit
somwhere in China, passed all the way thru the earth to erupt here in a
volcano. Yea right lol!
Have a nice day
Steve
