Diamonds are graded according to cut, colour, clarity and carat weight. When cutting a rough diamond stone, the diamond cutter first determines the natural colour of the stone, then plans a cut that preserves the highest carat weight for its maximum clarity.
So the highest grade of diamond is the largest stone with zero flaws in the rarest colour with the most perfect cut for that stone. These diamonds are sold at auction and bring millions of dollars to sellers.
In jewelry, the D colour is the highest grade colour; internally flawless is the highest clarity, blue and red could be the rarest natural colours.
The Gemological Institute of America's Web site will help you better understand the four Cs, below.
Finally, exceptional stones, are also graded according to the type of diamond, the most common being Type I. Read more about diamond types, below.

What is the range of how much a diamond is worth?
Given that you can purchase ultra-high-quality gem stone grade diamonds for millions of dollars US per carat or industrial-grade diamonds by the pound for a few dollars, there is a very broad range of the value of the mineral diamond. A gem-quality diamond is worth whatever someone will pay you for it. If you have one for sale, best practices dictate that you take the diamond to a certified gemologist and pay for an evaluation as to the diamond's cut, colour, carat weight and clarity. This will help you establish a fair market price you can ask for the diamond. On the other hand, you can buy industrial-grade diamonds by the pound for a few dollars -- if you buy in bulk.

Industrial grade that will be used to make drill bits and saw blades, about $2,000 on up (adjusting from prices thirty years ago).

For comparison, the Hope diamond, a rare blue diamond of about 43 carats, but with a storied history and a curse, is worth 200 to 300 million dollars. __________________ If, on the other hand, you're asking about a 10 karat ring (karats measure metal purity: carats measure diamond weight), the metal in the ring can be worth up to 10/24ths of the spot price of gold on the day that you sell it.
