Is there a process whereby we don't have to buy any more equipment
to polish the sharp edges and bring the edge up to a high shine?
We have a Foredom tool and many abrasive wheels.
If you are just after a quick and dirty to make is look better than
just the saw cut; get yourself a pack of wet/dry sanding paper.
Depending on how clean your cut is, you start in the 200 - 400 grit
range, and just rubbing the flat on the paper (spritz it with water
from a spray bottle) on a known flat, smooth surface (I’ve got some
heavy safety glass shelving salvaged from an old entertainment
center, for stuff like this) until you get the saw marks gone. Then
you keep stepping up grits until you get to a pre-polish you can
tolerate (for most colored stones, 600 or 1000 is enough).
After that, depending on the stone, you can use tin oxide (white
rouge) if you want to go “old school”. Softer stones will gloss up
pretty well with stuff like Zam. Different stones respond to
different polishes (and polish applicators).
If you want to speed up the process, you can invest in a cheap palm
sander, and clamp it upside down in a bench vise. Just don’t use so
much water that it runs into the motor. You don’t need very much,
just enough to keep the stone from dragging on the abrasive paper.
