Shungite Tumbled Stones
Shungite tumbled stones from Karelia in north west Russia which is the world's main supplier of this curious mineraloid. Early studies were carried out on material from a deposit close to Shun'ga Village which is how the name shungite came about. Although it's reported to also have been found in a few other locations around the world, the Lake Onega region of Karelia not far from the border with Finland is the original deposit and by far the most well known.
A rare form of non crystalline carbon that contains traces of fullerene, shungite is highly sought after for use in alternative therapies such as crystal healing. It's also widely used for water purification purposes. This curious material is approximately two billion years old and is surprisingly light weight. It has a smooth texture and its colour is caused by the presence of carbon.
Shungite is correctly classified as a mineraloid not a mineral because it does not have a significant crystal structure. Other examples of mineraloids include obsidian which is volcanic glass, pearl, moldavite which is a tektite and amber to name just a few.
The shungite used for tumbling is a lower grade than the material known as elite shungite which contains a much higher percentage of carbon. For this reason tumbled shungite tends to be considerably cheaper. The pieces in our collection come in different shapes and sizes and exhibit a dull lustre. This term is used to describe the way that light interacts with the surface of a stone. Dull means that it absorbs light whilst vitreous means it reflects light in a similar way to glass.
It's quite difficult to give an approximate size for our shungite tumbled stones because they come in many different shapes and sizes. We have however given a range of weights but please note, weights do vary slightly from piece to piece.
