This is too general of a question. It would depend on the stone size and quality. It would also depend on the finished cut for comparison, i.e. the 4C's (cut, color, clarity, and carat.) It would also depend on where the diamond was mined, who the cutter was, and many more things.
Gem quality diamonds are the ones that are cut into jewelry. They are a better quality as far as color and clarity. A 10CT rough stone may only have a 2CT section that is good enough to be cut. Then by the time that section is cut, shaped, and polished, you may only have a 1CT diamond.
The other end is the mineral stone. They are still a diamond, but due to poor color, or too many carbon deposits, they cannot be used for jewelry. They are the diamonds that are used for anything that has diamonds other than jewelry, commonly ground into a powder form, i.e. diamond powder used in nail polish, the coating on drill bits, metal polish, etc...
The average uncut diamond is mostly a mineral quality, and only a small part good enough for gems. So it would probably be a very low percentage value of the of the finished, cut stone. Somewhere between 10-30 on your 100 price scale, but it really all depends on the stone.
