It is possible, but you would essentially have to buy an unpolished stone or the ore a diamond is found in. Barring that, diamonds will have some value regardless of their clarity level. The type of stone you are talking about is the kind used in industry in saws, scalpels and other types of cutting equipment as well as sandpaper.
It is important to keep in mind that the clarity grade is only one of the factor that affect a diamonds price - jewelers and appraisers also consider the color, the cut and the weight. That is because it is possible to have a stone that has low clarity but has excellent color, cut and weight.
