Yes, tumbled stones are real stones. They are typically small pieces of natural gemstones or minerals that have been polished and smoothed through a tumbling process. This process gives them a shiny and smooth appearance, making them popular for use in jewelry, crafts, and crystal healing practices. Tumbled stones retain the metaphysical properties of the original stone, making them a popular choice for those seeking their healing benefits. **

To determine if your tumbled stones are genuine, you can start by examining their appearance and texture. Genuine tumbled stones will have a natural, unpolished look with no signs of machine polishing or artificial shaping. You can also check for any natural imperfections or inclusions that are typical of authentic stones. Additionally, conducting a scratch test using a piece of glass or a steel file can help you assess the hardness of the stone, as genuine stones will not be easily scratched. Finally, seeking the expertise of a professional gemologist or using specialized testing equipment can provide a more accurate assessment of the authenticity of your tumbled stones. **
