While polishing a piece of the Havero meteorite that fell to Earth in Finland in 1971, researchers discovered an intensely rich carbon-loaded spot that could not be smoothed by a diamond containing polishing paste. A closer look at the meteorite revealed two completely new kinds of naturally occurring carbon structures that are harder than diamonds formed within the Earth.
Such “super diamonds” had been predicted to exist decades ago but have never before been found in nature. Researchers found that these “super diamonds” consist of fused graphite sheets similar to artificial diamonds. The discovery will help scientists gain a better understanding of carbon polymorphs and give them material to investigate and possibly synthesize super diamonds.
Will this devalue the worth of your diamonds! Of course not! Diamonds are still beautiful! Just an interesting little tidbit of new information
