All of our Minerals & Crystals are 100% Genuine Specimens & come with a Certificate of Authenticity

These are special Tumblestones that have been produced from some of the most beautiful, and sometimes hard to obtain, minerals from around the world. These specimens are sold as individual stones.

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.

Onyx is a cryptocrystalline form of quartz. The colours of its bands range from white to almost every colour except shades such as purple and blue. Commonly specimens of onyx available contain bands of colours of white tan and brown. Pure black onyx is the most famous variety and has a long history of use for hardstone carving and jewellery.
