The value of a diamond depends on its cut, its clarity, its colour and its carat weight. A local jeweler can give you the answer you want.
A flawless stone of this size is extremely rare. Take your diamond to a certified gemologist, who will certify that the diamond is indeed flawless, and who will help you describe the stone otherwise: its colour and cut will also affect its price.
A diamond is worth whatever someone will pay you for it. Depends on the diamond. A diamond's value is determined by carat, color, cut and clarity. There are many grades of diamonds from industrial grade to Flawless, gem quality.
Every diamond is valued according -- not only to its clarity and colour, as above, but must include its cut and carat weight in addition.
Your diamond may be a black diamond, if it's a diamond. There is a black diamond scale which ranks stones with AAA grades. Diamonds that are flawless are labeled IF for internally flawless, or FL for flawless. This stone could also be something other than a diamond. Only a gemologist can give you the value, based on its cut and determination of how the stone achieved its colour.

The diamond could be a Deep Fancy yellow, blue, pink, or other colour. There, the price will be established by the bidders in the room at the time of sale. A deep fancy coloured diamond that is flawless and large will probably cost you more per carat than the D colour diamond, above.
