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.
 
Dalmatian Jasper
Dalmatian Jasper is a stone that encourages the breakdown of barriers. The black spots running throughout are Black Tourmaline, and will aid with your journey to spiritual grounding and protection. It is particularly beneficial for those who are overly analytical, returning some of the intellectual carefulness back into the physical joy of simply being. Dalmatian Jasper has a grounding energy, supportive of family and loyalty, and has a calming influence for children and animals.
