Shungite is a unique coal-like stone from Russia. Almost 2 billion years in age, this mineral is hailed for its healing power, hence it has been labelled a miracle stone. Each tumblestone has been tumble polished, a process that smoothes and polishes the crystal to reveal its unique colour and form. Tumble stones are a wonderful way to enjoy crystals, whether for their beauty or healing powers. Tumble stones are perfect as healing stones, easy to carry with you or to offer as a crystal gift for those who could benefit from them. A stone not only for the esoteric enthusiast but for the crystal collector as well, these tumbled stones are an inexpensive way to develop a large and attractive collection.
