    There are many different abrasive materials available and I've read
    the catalogue descriptions. I still don't understand what the real
    differences between them are, as they all sound like they do the same
    things. I would appreciate feedback on which abrasive experienced
    jewelers use for what purpose. I am particularly interested in
    cleaning out the inside of rings that have been sized up. Cost
    effectiveness is also an issue as I size up about 40 rings each day. 

    I've used the aluminum oxide cartridges, but they "blow apart",
    rather than wear down, once or twice a week. The guys in the shop
    all use these. They don't use the sanding bands, saying they have
    the same "flying apart" problem. 

    The trizact bands barely lasted through 1 ring before becoming
    uselessly dull. I tried these with and without Stuller's lube. 

    The 3m Imperial micro-finishing film is great for use on a sanding
    stick, but wears out too quickly in the small bands. 

    I love the 3m flex diamond bands, but they're really expensive. The
    other band abrasives I'm aware of include: Silicone carbide, 3m
    Cubitron ceramic (Purple), 3m Trizac CF (Green), and 3m Diamond
    microfinishing bands. I thank you in advance for your feedback on
    what abrasives you use, and those you don't care for.
