    Diamonds are neither rare nor extremely valuable, big ones are usually better off being cut up.

    Synthetic diamonds are harder than natural ones:


    "In May 2015, a record was set for an HPHT colorless diamond at 10.02 carats. The faceted jewel was cut from a 32.2-carat stone that was grown within 300 hours."

  3. I am assuming this will be used for industrial purposes, like most synthetic diamonds?
