From jewellery makers to landscapers, the fabled rock tumbler has been a useful tool for cleaning and polishing rocks for centuries.<\/p>\n

A tumbler can be a great addition to your practice, or it can simply be a great way to learn about geology and mineralogy.<\/p>\n

The process is fairly simple. The rocks are placed in a tumbler with abrasive grit and water. It then rotates for a period of time, causing friction between the rocks and the grit and producing smoothed and polished surfaces.<\/p>\n

The result is a polished rock, displaying colours and patterns, often making them smooth and shiny.<\/p>\n

Tumblers can come with a range of materials, capacities and purposes. To help you navigate the rocky shores of the tumbler market, we\u2019ve listed our top picks below.<\/p>\n
