Tumbled stones are rocks and minerals that have been smoothed, shaped and polished in a rock tumbler. With them being natural stones minor anomalies or "imperfections" are not uncommon. Due to the way they're produced it's rare for any two stones to be exactly the same.
This type of stone can also be cut and polished by hand. When produced in this way they tend to be round, oval or dice-shaped. Despite not having been produced in a rock tumbler, they're still known as tumbled stones.
The tumbled stones in this section are smaller sizes.
