Material properties of diamond - Wikipedia
It has been shown that some diamond aggregates having nanometer grain size are harder and tougher than conventional large diamond crystals, thus they perform better as abrasive material. [3] [4] Owing to the use of those new ultra-hard materials for diamond testing, more accurate values are now known for diamond hardness.
