Kornerupine is a rare borosilicate mineral formed under metamorphic pressure, valued in South Asian and East African healing traditions for restoring emotional circulation. Unlike heart stones that force cathartic release, kornerupine helps what's been stuck begin moving again—like blood flow returning to a numb limb. Sound healers reach for it when clients are emotionally exhausted or when their own reserves need restoring without dramatic purging.
This bowl serves caregivers, therapists, teachers, and anyone who's been managing others' emotions so long they've lost touch with their own. It's for the person running on empty, the strong one who forgot to refill, the professional whose heart has become a functional tool. Parents use it for bedtime grounding, team leaders for meeting openings, and wellness practitioners for restoring their capacity between sessions.
This bowl sounds at 258 Hz in the root chakra range, creating an unusual combination: heart opening that stays anchored in the body. Kornerupine's emotional circulation properties meet a deep foundational tone, so release doesn't scatter—it settles. Practitioners report breath deepening before conscious relaxation, shoulders dropping as sound moves through hips and lower spine. Heart work that lands in your sitting bones, not just your chest.
Rose quartz offers gentle receptive opening; kornerupine restores circulation. Where rose quartz invites softening, kornerupine addresses stagnation—the exhaustion of a heart that's been working overtime. Its metamorphic formation (mountains becoming themselves under pressure) carries patient transformation rather than immediate catharsis. Choose kornerupine when you need change that anchors through the body, not emotional release that requires recovery time afterward.
At 258 Hz with -40 cents, this bowl sits below concert pitch in the Grounding range, producing a warmer, more organic quality that settles into the body rather than floating above it. This frequency also aligns with A=432 tuning, often called "natural tuning." When kornerupine's heart-opening circulation meets this deep foundational tone, the result is emotional work that doesn't require you to leave your body—ideal for morning rituals before demanding days or evening recovery after caregiving.
Every bowl includes a pure quartz mallet wrapped in premium silicone for optimal resonance with the 258 Hz frequency, plus a silicone O-ring for stable playing on hard surfaces.Â
