Like mined diamond, lab grown diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. It’s absolute hardness is 140 times that of the next hardest material.
The hardness of diamond contributes to its suitability as a gemstone. Because it can only be scratched by other diamonds, it maintains its polish extremely well. Unlike many other gems, it is well-suited to daily wear because of its resistance to scratching—perhaps contributing to its popularity as the preferred gem in engagement or wedding rings, which are often worn every day.

Many technological applications are enabled singularly by diamond. As technology progresses, more and more advances will need to utilize one or the other extreme properties of diamond to enable such advances.
Relative to Silicon, diamond can run at 5x higher temperature without degrading in performance. It has 22x the heat transfer efficiency of Silicon, allowing it to be cooled easily. A thin piece of diamond can tolerate grid transmission level voltages. Diamond based semiconductor devices have been shown to deliver 1 million times the electrical current than Silicon based ones.
