Smithsonian scientists also observed huge figures of very small diamonds when they had been slicing a sample with the Allen Hills meteorite [seven]. These diamonds in meteorites are believed to get shaped in House through higher-pace collisions just like how diamonds variety on Earth at influence web sites.
