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.
This depends entirely on the diamond in question.
Testing a raw diamond at home can be challenging without the proper equipment. One common method is using a diamond tester, which measures a diamond's thermal conductivity to determine if it's real. Alternatively, you can check for imperfections or inclusions under a jeweler's loupe, though this method is less reliable. Consulting a professional jeweler is the most recommended way to accurately test a raw diamond.
A raw diamond will have a rough, unpolished surface with a dull appearance. It may also appear cloudy or opaque due to impurities. If you are unsure, it is best to have the diamond evaluated by an expert gemologist.
Raw diamonds are processed by cutting and polishing them to enhance their natural beauty and maximize their brilliance. Initially, the diamond is analyzed to determine the best way to cut it, followed by shaping it into a specific design. Finally, the polishing process smoothens the facets and gives the diamond its characteristic sparkle.
The field test for a raw diamond is 'extreme hardness'. Otherwise, pick up the stone and take it to a jeweler, who may be able to confirm that you have picked up a diamond and not another clear mineral.

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.
When raw diamonds are cut and polished, a 'diamond dust' is released. It is collected and re-employed in the diamond polishing process.

Maybe. Your local jeweler can apply a probe to it, to determine whether or not it is a diamond stone.
Manufacturing firms typically hold inventories of raw materials, components, work-in-process, and finished goods. Retailers and wholesalers also hold inventories of finished goods for sale to customers.
The proper words are raw diamond, raw stone, rough diamond, uncut diamond -- all are appropriate.
WIP is Work in Progress/Process. Not raw material or finished goods but in between.
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.
This depends entirely on the diamond in question.
