The Meinl Sonic Energy Marble Crystal Singing Bowls made of high-purity quartz create a very pleasant aura with their sound and design. Their long-lasting, spherical tone spreads when the singing bowl is gently tapped or rubbed so that the energy can be felt in the entire surroundings. The beautifully marbled color of the singing bowls is oriented to the respective matching chakra. You can use Crystal Singing Bowls for a variety of purposes: Chakra healing, meditation, sound therapy, yoga, improving your home Fengshui, adjusting your emotional state, or even for room decorating. Each crystal singing bowl comes with a white silicone ring to avoid possible impact and to ensure the best resonance.
