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 doesn¹t 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 doesn¹t flow 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.
