Diamonds are rated according to the colour, clarity, carat weight and cut.
Black diamonds are more porous and from younger sedimentary rocks, so they are not as expensive as other diamonds.
Whatever you have to sell is worth whatever someone will pay you for it. The uncut diamonds could be industrial diamonds or gemstone-quality diamonds. Eighty percent of all diamonds mined are industrial diamonds, which you can purchase very cheaply. Take your uncut diamonds to a diamond cutter for an in-person conversation about the value of each or of the cache.
No, chocolate diamonds are usually less expensive than regular -- white -- diamonds, given equal cut, clarity and carat weight.
The most common use of diamonds is for industrial tools, because industrial diamonds are the most common diamonds.
By weight, diamonds are worth more because they are much more rare than gold.
Yes. Exceptions are gem-quality diamonds that have been cut and polished so that there are no flaws. These diamonds are rated as 'flawless'.
