Tumbled stones

Tumbled stones are crystals that are worked into a shiny, smooth stone, like those found in a river or stream. In fact, nature carries out a tumbling action in a natural way, smoothing the stones and making them smooth. The tumbling technique is based on the same principle: tumbling is a slow process by which the stones are vibrated and rolled in large tanks with abrasive powders. The rotating movement of the tumbler gives the stone lucidity and makes it smooth. Tumbling is a technique also known as tumbling.
