    I'm not sure that's the case. If the rough was all the same hue,
    tone and saturation when starting, the significantly larger
    briolette will always be darker than the smaller, 6mm beads. It's a
    question of the amount of material that light must pass through
    before it hits your eyes. Since the briolette is much larger, it
    will always be darker. I don't think the beads have become lighter
    due to the drill hole, and no amount of polishing is going to make
    them the same color as the much larger briolette. You probably
    should have sold your customer a lighter-toned rough for the
    briolette. 

    I've never polished the inside of a drill hole, but if I had to do
    it by hand (51 of them? yikes!!!), I would try stringing them on a
    strong thread charged with diamond paste, similar to a "thrum" that
    goldsmiths use to polish inside metal. I hope somebody else has a
    simpler, less work-intensive method for you. But I still think the
    problem is the size disparity between the beads and briolette.
