High quality tumblestones at 2-4cm in size. You can either buy these as single stones, or benefit from quantity discounts by purchasing larger amounts.
Tumblestones or “tumbled stones” as they are also referred to are made by “tumbling” rough crystals, minerals or rocks in grit for a number of days in a tumbler machine. Different grades of grit are used in the process until the rough edges are smoothed, then polish is added to bring a soft shiny surface to the specimen. Because of this process each stone will be unique in shape and colour.
