Materials harder than diamond

These substances can scratch diamond:

• Some diamonds are harder than others.
• Borazon
• Cubic boron nitride
• Ultrahard fullerite
• Rhenium diboride
• Aggregated diamond nanorods
• A material called lonsdaleite (also called hexagonal diamond), confirmed to be 58% stronger than diamond and is the hardest material known to date.
• Aggregated diamond nanorods, a material created using ultrahard fullerite (C₆₀)
• Wurtzite boron nitride
