This 8" opaque quartz crystal singing bowl sounds in F# at 363 Hz, resonating with the higher heart chakra and the core of the body—chest cavity, heart, lungs, and mid-spine. Opaque quartz, also called milky quartz, is pure crystalline silicon dioxide—the same gemstone as clear quartz, distinguished by its soft, luminous appearance and smooth, river-stone texture.

ESSENCE

I am the stone that learned to sing. When your thoughts have scattered across a hundred directions, when the noise inside grows louder than the noise outside, I offer something simple: space. Not answers—space. The kind of quiet where you can finally hear yourself think. I don't arrive with drama. I come as clarity itself, the sort that settles rather than shouts. Listen through me, and you may find what was there all along.

THE ELEMENT

Opaque quartz is silicon dioxide in its purest crystalline form—the same mineral as clear quartz, distinguished by microscopic inclusions that scatter light and create its characteristic milky luminosity. This variety forms within igneous, metamorphic, and sedimentary rock systems worldwide, making it one of Earth's most abundant and enduring minerals. Ranking 7 on the Mohs hardness scale, quartz is harder than steel, capable of scratching glass, and built to last.

For over 100,000 years, humans have shaped quartz into tools, vessels, and sacred objects. Ancient Egyptians carved it into amulets. Medieval alchemists saw its crystalline perfection as a symbol of ordered matter. Modern science discovered its piezoelectric properties—the ability to convert pressure into electrical charge—making quartz essential to everything from precision timekeeping to radio transmission.

When opaque quartz is formed into a singing bowl through Divine Bowls' proprietary molding process, the mineral's molecular structure becomes part of what vibrates. This isn't a coating or surface treatment—the quartz itself, with its soft luminosity and grounding presence, is the instrument. People often describe this bowl's tone as warmer and more enveloping than clear quartz, with a quality that feels like being held rather than illuminated. Working with opaque quartz invites you into presence without demand. It creates conditions for mental spaciousness, for the kind of clarity that emerges when you stop trying to figure everything out.

THE FREQUENCY

This bowl sounds in F# at 363 Hz, resonating with the higher heart chakra in the Western diatonic system. The higher heart sits between the heart and throat—a bridge point associated with compassion, self-acceptance, and the integration of feeling and expression. This frequency vibrates through the torso, chest cavity, and mid-spine, carrying an energetic quality of manifestation and thought-form.

When opaque quartz's clarifying presence meets the F# frequency, something interesting happens. The mental clarity this mineral supports finds a home in the body's core—not floating in the head, but anchored through the chest. People often notice a settling quality, as though scattered thoughts are finding their natural order without effort.

THE TUNING

This bowl resonates at 363 Hz. Using A=432 as reference, it plays F#-1—essentially a true-tone F#. Using A=440 as reference, this same frequency is F#-32.

This bowl is categorized in the A=432 tuning because its frequency aligns with instruments tuned to A=432 Hz—often called "Verdi tuning" or "natural tuning." Many people find A=432 produces a warmer, more organic quality that feels easier on the nervous system. If you have instruments tuned to A=432, or simply prefer this earth-connected sound, this bowl will harmonize beautifully with them.

(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 8 inches, this bowl produces fourth-octave tones with medium-long sustain—meaning each strike rings out fully before gently fading, giving you time to breathe with the sound rather than chase it. The full, projecting volume fills small to medium spaces without overwhelming them: a living room, a classroom, a therapy office, a conference room before the day begins.

This size allows opaque quartz's grounding clarity to express with presence and warmth. The bowl is substantial enough to feel like a real instrument, portable enough to move between rooms or bring to a retreat. The fourth-octave resonance naturally targets the core of the body—chest, heart, lungs—making it particularly effective for work that involves centering, focus, or simply coming back to yourself.

WORKING WITH THIS BOWL

Reach for this bowl when your mind feels cluttered, when you've been thinking in circles, or when you simply need a moment of quiet before the next thing begins. You don't need training or technique—just willingness to listen.

Place the bowl on its O-ring on any stable surface. Hold the mallet gently, strike the rim, and let the tone fill the space. You might close your eyes. You might take three slow breaths. Notice what happens in your chest, your shoulders, the space behind your eyes. This bowl works well at the start of a workday, before a difficult conversation, during a study break, or as a signal to children that it's time to settle. Teachers use bowls like this to mark transitions. Athletes use them before visualization. Writers use them to clear the mental static before entering a project. There's no wrong way—only your way, discovered through use.

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 use.

INVITATION

This bowl isn't trying to convince you of anything. Opaque quartz doesn't work that way—it just offers what it is: clarity without agenda, presence without demand. The kind of quiet that lets you hear your own thinking again.

Maybe you're a sound healer building your collection. Maybe you're a teacher who needs something to settle a classroom. Maybe you're someone who just wants three minutes of stillness before the day starts asking things of you. The bowl doesn't mind which. It rings the same F# either way—363 Hz of milky luminosity, formed in a single seamless vessel, ready to outlast whatever brought you here.
