Borazon, a boron nitride allotrope, is the fourth hardest substance, after aggregated diamond nanorods, ultrahard fullerite, and diamond, and the third hardest artificial material. Borazon is a crystal created by heating equal quantities of boron and nitrogen at temperatures greater than 1800 °C (3300 °F) at 7 GPa (1 million lbf/in²). Borazon is the only substance other than those listed above that can scratch a diamond  (although lasers can cut diamond). A diamond will also scratch Borazon.

Uses and production
Borazon is used in industrial applications to shape tools, as it can withstand temperatures greater than 2000 °C (3500 °F), much higher than that of a pure diamond at 871 °C (1600 °F). Other uses include jewellery designing, glass cutting and laceration of diamonds.
