This opaque quartz crystal singing bowl sounds in F#/G at 378 Hz, resonating with the higher heart chakra and the chest cavity, lungs, and core. Opaque quartz—pure crystalline silica with a soft, milky luminosity—supports emotional settling, gentle boundary-setting, and the slow work of self-compassion. When this mid-range frequency meets quartz in its most tender form, the result is sound that wraps around rather than pierces through.

BEST FOR

  • Emotional regulation and gentle nervous system support
  • Caregivers needing restoration between giving to others
  • Teachers creating calm transitions in busy classrooms
  • Those navigating grief, stress, or uncertain life passages
  • Therapists and counselors holding space for difficult emotions
  • Evening wind-down and releasing the day's accumulated tension
  • Anyone overwhelmed by intensity who needs softer medicine

ESSENCE

I am the softness inside the stone. Where my clear siblings refract light into rainbows, I hold it gently, diffusing brightness into something the weary eye can bear. When you've been striving too long, when the sharp edges of ambition or grief have worn you thin, I offer what a clean linen pillowcase offers after a difficult day—a place to rest without pretense. You don't have to be transparent right now. You don't have to see through to some ultimate truth. I hold space for the cloudy days, the unclear feelings, the slow process of integration that happens in fog and milk-light.

THE ELEMENT

Opaque quartz is pure silicon dioxide—the same composition as clear crystal quartz, formed under the same geological pressures over millennia. The difference lies in what happens during formation: microscopic inclusions of air and fluid create the soft, milky appearance that distinguishes this stone. Like milky quartz found in nature, this opacity isn't a flaw but a characteristic—some quartz simply wants this tender, diffused quality.

Throughout history, people have reached for milky quartz when they needed gentleness rather than intensity. Aboriginal Australian traditions used it in rain-making ceremonies to invoke balance. Ayurvedic practitioners recommended it for cooling overheated constitutions. European crystal traditions employed it for scrying when softer visions were sought. The common thread across cultures: this is the quartz you turn to when you need protection without walls, strength without hardness.

When you work with opaque quartz, you're working with the gemstone itself—not an infusion of something else into quartz, but quartz in one of its most nurturing natural expressions. Divine Bowls' proprietary process creates this milky luminosity throughout the entire vessel during formation, resulting in a microstructure that produces distinctly softer, more enveloping tones. People often describe the sound as "rounder" or "warmer" than clear quartz—frequencies that wrap around defended places rather than demanding entry.

THE FREQUENCY

This bowl sounds in F#/G at 378 Hz, resonating with the higher heart chakra in the Western diatonic system. The higher heart—sometimes called the thymus or etheric heart—sits between the heart and throat, governing compassion, forgiveness, and the bridge between feeling and expression. This frequency carries the energetic quality of manifestation and thought-form, vibrating through your chest cavity, lungs, and core.

When opaque quartz's gentle, diffusive energy meets this heart-adjacent frequency, something subtle happens. The combination supports emotional processing without forcing catharsis, creates space for feelings to surface at their own pace, and helps soften the defended places where old hurts live. People often notice their breathing deepens naturally, their shoulders drop, and the racing mind begins to settle like silt in still water.

THE TUNING

This bowl resonates at 378 Hz. Using A=440 as reference, it plays F#+40 cents. Using A=432 as reference, this same frequency is G-31 cents.

This bowl is categorized in the C=528 tuning because its frequency aligns with instruments tuned so that middle C equals 528 Hz—known as the "Love Frequency" in Solfeggio tradition. This brighter tuning carries heart-opening qualities and a gentle uplift that complements opaque quartz's softening nature. The slightly elevated pitch creates clarifying resonance without the intensity of sharper frequencies—brightness tempered by the milky quartz's inherent gentleness.

(For fine adjustment, adding water to the bowl lowers the pitch slightly—a technique some use to dial in precise intervals when playing with other instruments.)

THE SIZE

At 7 inches, this bowl produces fourth-octave tones with medium sustain—sound that rings long enough to settle into but doesn't overwhelm smaller spaces. The room-filling yet balanced volume makes it equally suited for personal morning rituals, therapy offices, classroom corners, or bedside tables. This size travels well between rooms and fits naturally into daily life rather than demanding dedicated space.

The 7-inch format allows opaque quartz's tender qualities to express with intimacy while the fourth-octave resonance naturally targets the torso and chest. For those who find larger bowls too commanding or smaller bowls too delicate, this middle ground offers versatility—substantial enough to fill a yoga studio, gentle enough for a child's bedtime.

WORKING WITH THIS BOWL

Reach for this bowl when you need permission to soften. After a day of holding space for others—whether you're a parent, caregiver, teacher, or anyone who gives more than they receive—this is the sound that says your turn now. Before difficult conversations where you want to speak truth without cutting. During transitions when the path forward isn't clear and you need to sit with uncertainty rather than force resolution.

Begin simply: place the bowl on a stable surface or hold it in your palm. Strike gently with the mallet and let the sound wash over you without agenda. Notice where your body responds—perhaps a softening in the jaw, a release across the shoulders, a deeper breath arriving unbidden. You might place one hand on your chest while the bowl sings, connecting the external vibration to your internal landscape. There's no wrong way to work with this bowl. The frequency doesn't require technique; it simply asks for your presence.

Each Divine Bowls singing bowl includes a pure quartz mallet wrapped in premium silicone for optimal resonance, plus a silicone O-ring for stable playing on hard surfaces. Every bowl is formed in a single seamless vessel from 99.995% pure quartz—no welds, no weak points—built to last lifetimes of gentle, unhurried use.

INVITATION

You've read this far—not because you needed convincing, but because something here felt familiar. Like recognizing a voice you've been listening for without knowing it.

This bowl doesn't ask you to be further along than you are. It doesn't require you to have the right credentials, the perfect meditation practice, or a dedicated sound healing room. It asks for something simpler: the willingness to soften. To let the day's accumulated tension settle like silt in still water. To remember that gentleness is also a form of strength.

Maybe you're a caregiver who needs care. A teacher who creates calm for thirty students but forgets to create it for yourself. Someone navigating grief or transition who's tired of being told to "just breathe" when what you actually need is permission to not be okay yet. Or maybe you're simply drawn to this particular frequency, this milky luminosity, this sound that wraps around rather than demands entry—and that's reason enough.

Not every bowl finds every person. But if you've stayed with this one, if something in the description made you pause and think yes, that—trust that. The bowl is here. You're here. The rest is just logistics.

Frequently asked questions

Here are some common questions about this bowl.

Opaque quartz produces acoustically softer, more enveloping tones due to its microstructure of microscopic air inclusions—the same characteristic that creates milky quartz in nature. Practitioners reach for opaque when clients need gentleness rather than intensity, or when clear quartz feels too piercing. It's not a lesser version; it's quartz in its most nurturing expression, ideal for emotional settling, caregiver restoration, and work with defended hearts that need permission to soften slowly.


This bowl serves anyone overwhelmed by intensity—caregivers needing restoration between sessions, teachers creating calm classroom transitions, therapists holding space for difficult emotions, and individuals navigating grief or uncertain passages. Unlike clear quartz that demands transparency, opaque quartz holds space for cloudy days and unclear feelings. Parents use it for evening wind-down, counselors for gentle nervous system regulation, and anyone who finds sharper frequencies too activating when emotional reserves are depleted.

At 378 Hz resonating with the higher heart chakra (thymus), this bowl bridges feeling and expression—supporting compassionate communication and forgiveness work. The opaque quartz's diffusive quality prevents the frequency from forcing catharsis; instead, it creates conditions for emotions to surface at their own pace. Practitioners use this combination for boundary-setting that doesn't harden into walls, self-compassion practices, and releasing accumulated tension from the chest and shoulders without overwhelming vulnerable clients.

Opaque quartz isn't infused with another element—it IS the gemstone. This is 99.995% pure silicon dioxide, the same composition as clear crystal quartz, formed with microscopic inclusions that create its milky luminosity throughout the entire vessel during formation. While infused bowls add herbs or minerals for specific intentions, opaque quartz offers the foundational properties of quartz itself: amplification, clarity, and universal receptivity. It's the bowl that holds space for whatever intention you bring, without agenda.

Yes—this bowl's 378 Hz frequency aligns with the C=528 tuning system, known as the "Love Frequency" in Solfeggio tradition. This brighter tuning carries heart-opening qualities, but the opaque quartz's inherent softness tempers that brightness into something accessible for overwhelmed nervous systems. The combination creates clarifying resonance without intensity—ideal for practitioners blending emotional release work with gentle uplift, or anyone building a C=528 collection who needs a bowl that won't overstimulate during vulnerable moments.

Each bowl includes a pure quartz mallet wrapped in premium silicone for optimal resonance with the opaque quartz's softer tones, plus a silicone O-ring for stable playing on hard surfaces (allowing the bowl to resonate freely). The bowl is formed in a single seamless vessel—no welds, no weak points—built to last lifetimes. At 7 inches, it produces fourth-octave tones with medium sustain and room-filling yet balanced volume, versatile enough for personal rituals, therapy offices, or classroom corners.
