The Meinl Sonic Energy Rose Quartz Crystal Singing Bowl is a pure union of Rose Quartz and Quartz Crystal. This beautiful singing bowl creates a very pleasant aura with its sound and design. A long-lasting, spherical tone spreads when the singing bowl is gently tapped or rubbed for a calm, soothing effect ideal for a variety of settings.  All Crystal Singing Bowls are delivered with a silicone ring to avoid possible impact and to ensure the best resonance. The corresponding heart chakra promotes confidence, optimism, warmth, cheerfulness, compassion, and helpfulness.
