Many cases rudraksha is worn above waist level to bring control over emotions. Wearing on waist still depends on the comfort and whether above or below naval is not that much important.

I feel the rudraksha beads are not easily damaged. After it has been dried up, it really becomes hard and general wearing does not bring any damage to the bead or it's quality. Sometimes the beads are recommended to be worn around waist. All can wear rudraksha around waist. When wearing on waist it may fell a sense of discomfort at times. But if the beads are strung properly and strongly then it will be easy and comfortable to wear. Rudraksha beads work better when they touch your skin. so keep the beads touching your skin. It can be worn around waist as per your comfort.
