✧ Opal Arcana ✧
440 Hz Curated Crystal Singing Bowl Set
Rare, luminous, and quietly enchanting, Opal Arcana is a four-bowl collection of F3, A#3, C4, and C5, brought together through soft pink, white opal, amethyst, and etched crystal.
At the foundation, the Pink Opal F3 offers warmth and depth without becoming heavy. Beside it, the A#3 etched Sunflower bowl is a truly distinctive instrument: white opal etched with a sunflower, with the world held within its centre. Auralith Sanctum C4 introduces soft amethyst and white into the middle register, while the White Opal C5 extends the collection upward in a clear, luminous voice.
Together, these four bowls create a field that feels spacious and suspended. The octave relationship between C4 and C5 brings a sense of continuity through the collection, while F3 and A#3 add depth, movement, and colour around it.
There is no need to understand the musical relationships to work with this set. Opal Arcana can be approached entirely through listening: following tone, texture, resonance, sensation, or simple curiosity. Some may be drawn to its openness and softness; others may connect more strongly with its imagery, its visual symbolism, or the way the harmonics move through the body and surrounding space.
The sunflower imagery at the heart of the A#3 may evoke growth, cycles, illumination, connection, or the relationship between the individual and the wider world. The opalescent finishes may suggest softness, possibility, or shifting perception. None of these meanings are fixed. They are simply invitations to notice what arises for you.
Visually, Opal Arcana feels almost luminous from within. Pink opal, white quartz, amethyst, and etched detail create a palette that is soft without becoming fragile, mystical without needing to be defined.
440 Hz sets are uncommon within Rainbow Tones, and this particular combination feels especially singular: two lower-register anchors, an octave of C, and four instruments whose visual and tonal relationships came together in a way that is unlikely to be repeated exactly.
