Hi Elain:

    Another interesting point we have found about sand vs glass beads is
    that because the individual sand particles are irregular and
    sharpish in shape, they will leave a mirror shaped or reverse image
    (irregular and sharpe) in the metal being blasted.  Because of this,
    dirt will adhere to the surface being treated more readily compared
    to a bead blasted surface.  The indentations in the latter do not
    seem as deep and because of the smooth nature of the glass beads,
    will not retain dirt as readily.  For these reasons, we will not
    apply a sand blasted finish to rings.  I hope this helps you.
