Black Obsidian Tumblestone 15–25mm Natural Volcanic Glass Crystal Stone Genuine Black Obsidian Tumbled Mineral Specimen

Description 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. Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimal crystal growth. Obsidian is commonly found within the margins of rhyolitic lava flows known as obsidian flows. As a healing stone, it is the ‘stone of truth.’ It can reveal many secrets, and it can answer your biggest questions about life and love. It can show you the meaning of the deepest mysteries of your life, the people you love, and the world in general. [similaras]
