Just stones?

Tumbled stones are small pieces of rocks and minerals (usually about one to five centimeters in diameter) that have been processed in a rock tumbler to produce smooth, rounded and highly polished pebbles. Most stones that a person can find will not tumble with good results. The rocks and minerals used to make tumbled stones are specially selected for their color, translucence, appearance and ability to
accept a high polish. These special materials are known as "tumbling rough". Some people collect their own tumbler rough and some buy it from a hobby supply store. Tumbled stones are often so beautiful that many people call them “tumbled gemstones.”

Tumbled gemstones are used to make jewelry, craft projects and other decorative items. They are also widely collected by people who appreciate their beauty and have always been associated with spiritual and healing properties by some superstitious people. They are especially enjoyed by children. Tumbled gemstones are extremely popular in gift shops – especially gift shops found at science centers, caverns and other natural science attractions. Many geologists obtained their first interest in rocks and minerals when they received tumbled stones as a gift or discovered them in a store.
