Raw stones are mined from the earth, separated from the surrounding material, sorted/ graded and then sold/ brokered to diamond buyers.

(Seventy-five percent of diamonds mined are employed in industry; only about 25% of mined diamonds are of gem quality.)

Diamond buyers/ brokers then move the gem-quality stones to cutting operations, where the raw stones are evaluated for colour and clarity. Plans are developed to highlight the colour and clarity of each individual stone while preserving the highest carat weight.

(About 60% of a raw stone's weight is lost in the cutting process.)

Then the stones are cut and polished, and sold to brokers/jewelers who mount the finished diamonds into jewelry.

What is the value of a diamond rock?

Your question is about a raw diamond. A raw diamond must be evaluated for its natural colour and clarity. Then you can work with a diamond cutter to estimate the value of a cut diamond that can be 'rescued' from the raw diamond. The diamond cutter may offer to purchase the raw stone, or work out another arrangement with you for its ultimate value. Typically more than 50% of the carat weight of a raw diamond is lost during the cutting process.

What unit of measure is used for diamond cutting?

Raw diamonds are cut based on a plan for the cut, which intends to preserve the raw stone's natural colour and the most of its carat weight possible. About 60% of a raw diamond's carat weight is lost in the cutting and polishing process. You can read more below about the American Institute of Diamond Cutting, which explains their curriculum, but lacks any named 'unit of measure' used in the process.
