    Looks like you've got a candidate for indirect lighting, that is lighting
    bounced off a reflector (a sheet, a wall, etc) instead of bounding off the
    polished stone directly into the camera lens.

    One solution that I have used applies white foamboard. Build it into an
    open-top box, say one foot across. Put your sample on a piece of black velvet
    fabric and then surround it with the box. Aim one or two lights into it, and
    they will bounce their light all around. I use Canon flash units, but you could
    just as easily use hot lights or anything if you are able to white balance.

  6. Take it outside on a cloudy day...put it in the shade if you can see any.
    That will help with most of the reflections....light on cloudy days is
    indirect and filtered. If you still have to remove more reflections try a
    polarizer filter. If you still see yourself...staple velvet to a sheet of
    cardboard...cut a small hole from which to shoot.

    As an alternative to photography, small pieces of polished rock can
    be scanned. With a good quality flatbed, you have the equivalent of
    quite a powerful microscope, if you want plenty of detail. Polarising
    filters can be used to great effect.

    It may be your best bet is a 'light tent.' Sometimes called
    [incorrectly I believe] a 'light box'

    Look at these pages:

    If this looks like what you need put homemade "light tent" in your
    favorite search engine and start surfing.

    Rule of thumb, all your lighting should be equaly `sharp'.
    The more specular the subject, the flatter the lights, difuse
    subject, smaller more directional lights.

    The other way for this sort of thing is crossed polarizers, but with
    rock the objective polarizer may act as an analizer and throw your
    colours way off.
