DiaBall is the open-source application for generation, modification and visualization of diamond balls of sizes up to 10nm (nanodiamond). Obtained molecules can be stored in PDB format.
With PDB format you can use obtained diamond balls to put hydrogen atoms with OpenBabel or any other radicals on a surface with Avogadro.
