The placebo effect can be explained as a response other than the specific influence of a treatment which comes from the psychosocial forces surrounding the treatment. This effect can be observed all over the world when people use healing stones. In this study, the perception of healing stones was investigated using the questionnaire technique. A popular online site helped reach 415 volunteers who participated in an online survey. Evaluation of the results revealed that gemstones, which are promoted as healing tools and give hope for getting better, have a positive ef-fect on people. On the other hand, even if gemstones are preferred only for use as ornamental stones, jewelry and accessories, then no positive effect is expected from their healing power.
