Well, what if it's done randomly? (like, by software that controls the machine that grows it)
Or, modify the growing process so that it has a greater element of chance to it? (this is likely multi-dimensional)

A diamonds primary value is the history of it's making. People are unfortunately always going to be paying more for a diamond which has been digged out by hard labour than created in a lab.
Keep in mind the value of diamonds is mostly a perceptive one. I am pretty sure if you only did synthetic diamonds it would soon fail to be valuable as the "womans best friend"
