In the field, you can identify a raw stone because of its clarity and its extreme hardness.
Raw diamonds come in many forms, sizes, colours and mixtures of geological materials.Take your raw diamond to a certified gemologist, who can help you identify the stone.
The proper words are raw diamond, raw stone, rough diamond, uncut diamond -- all are appropriate.
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.
This depends entirely on the diamond in question.
An uncut diamond can be 'field tested' for its extreme hardness. Also, you may be able to see light through it, since diamonds are essentially transparent -- to light. Diamonds conduct electricity, so a diamond tester probe would confirm that the raw stone is a diamond.
You're asking about a raw diamond, one that has not been cut or polished. In context, sometimes a raw diamond's "... eight corners are truncated by the eight faces of the octahedron." This is one description of a diamond's raw, crystalline form. You can read more about the geometric descriptions of raw diamonds, below.
The raw diamond of 19.5 carats weighs about 3900 milligrams. Remember, though that raw, gem-quality diamonds can lose about 60% of their weight when cut and polished.
A raw diamond looks like two square pyramids attached at the base.
With every diamond comes a certificate
The diamond cutter taught the intern how a diamond cuts diamond as they cut and polished the raw stone.
Industrial raw diamonds are much less expensive that gem-quality raw diamonds. You can visit the site, below, and look for the raw diamond that you want to buy.
examples of raw materials are Diamond, Suger and Aluminum.
