Tumbling

Term from Jewelry Making industry explained for recruiters

Tumbling is a basic finishing method used in jewelry making where rough stones, metals, or jewelry pieces are polished to a smooth, shiny finish. It involves placing materials in a rotating barrel or machine (called a tumbler) with abrasive materials and water. This process is similar to how ocean waves naturally smooth beach glass and stones, but done in a controlled way. It's an essential technique for both production jewelry making and craft jewelry making, making it a valuable skill for jewelry makers and metalworkers.
