Cabochon Machines at Discount Lapidary Supplies Home Page
To use the polisher just take a dopped cabochon that has been ground on a 220 grit grinding wheel and apply a dab of 325 grit diamond compound to the first hub on the polisher. Work the stone into the 2 inch section of the revolving spool. The gem is then wiped clean and the next finer grit is applied to the adjacent section.
