The color-frosted Meinl Sonic Energy 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 surrounding. All Crystal Singing Bowls are delivered with a white silicone ring to avoid possible impact and to ensure the best resonance. This bowl has a diameter of 8" / 20 cm and vibrates in note B4. The corresponding crown chakra promotes perfect understanding, fullness, and connection with the divine origin. 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.
