What Are Tumbled Stones?

Tumbled stones are small, rounded, brightly polished pieces of rocks and minerals. They are made by placing rough rocks in a machine known as a rock tumbler, which tumbles them until their edges and surfaces are smooth and polished. They are also known as “polished stones,” “tumbled gems,” “baroque gems,” “polished rocks,” and a variety of other names. (Source

Because you have to keep a tumbler running 24 house per day for 7 days the Recreation Center will not allow us to tumble stones at Seabreeze.  However, some of our members have been tumbling stones at home. These members are willing to help new members that are interested to tumble to learn how to tumble stones.
