Diamond is a good electrical insulator, having a resistivity of 100 GΩ⋅m to 1 EΩ⋅m [32] (1.0 × 10 11 – 1.0 × 10 18 Ω⋅m), and is famous for its wide bandgap of 5.47 eV. High carrier mobilities [ 33 ] and high electric breakdown field [ 34 ] at room temperature are also important characteristics of diamond.
Alexander Weindling, a third-generation diamond jeweler and the CEO of lab-grown diamond company Clean Origin, told The Guardian there’s a generational divide over accepting lab-grown diamonds ...
Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa.
