There’s no better way to introduce your students
to a classic lapidary process than with this economical
tumbler kit. Show the emerging beauty
of seemingly “ordinary” rocks and minerals,
while helping your students more clearly discern
their unique physical properties. The tumbler’s
quiet, all-rubber barrel makes rock-polishing as
pleasing to the ear as it is to the eye. It comes
with assorted rough gemstones, premeasured
abrasives, polish, and instructions. 110 VAC with
a 6’ cord.
