Thumb stones are smooth, polished gemstones, usually in the shape of an oval with a thumb-sized indentation, used for relaxation or anxiety relief.
They are used by holding the stone between the index finger and thumb and gently moving the thumb back and forth across the stone. This action of moving the thumb back and forth across the stone can reduce stress, and aid relaxation and meditation.
The smoothness of the stone is most often created naturally by running water.
Black Obsidian is a grounding stone that is thought to provide stability, protection from danger, and the ability to be more productive on all levels (physical, mental, emotional, and spiritual). It’s the perfect crystal for turning negative energies into positive benefits in one’s life, by helping us to see the truth in situations and to change restricting beliefs and behavioral patterns. It is thought to help reduce anixety, sharpen our senses and intellect, and is especially helpful for dissecting beliefs and habits that have been passed down to us by our families, allowing us to decide for ourselves whether these ideas are true and useful.
