The C-tone and the meaning of 432 Hz
This 20 cm crystal singing bowl is tuned to the C-tone at 432 Hz base frequency. 432 Hz is among the natural tone pitches: a significant part of classical music was originally composed around this tuning. Listeners often describe the tone as softer and rounder compared with 440 Hz. Whether you are looking for a bowl for quiet meditation or home sound work, this C-tone model offers you an even, balanced base vibration.
Material and craftsmanship
The bowl is made in China from powdered, pure quartz crystal in a process heated to several thousand degrees. Under the high heat the crystal grains fuse, and this is how the bowl's unified, solid wall is formed. The violet colour is integrated into the material as part of the form, so it will not wear off over time. Diameter 20 cm, weight around 1860 grams.
Where it serves you
At home it fits the living room, a meditation corner or the bedroom. It is just as suitable for a few minutes of morning attunement as it is for an evening wind-down. Yoga teachers and sound therapists often use it in group sessions too. Place the bowl on the supplied rubber stability ring on a flat, level surface, and circle the mallet slowly and evenly along the rim. After a minute or two the sound has fully opened. Kept in a permanent spot, it also makes a beautiful display.
Safety and care
The crystal bowl is fragile, so always place it on a flat, stable surface and never strike it hard. Never lean directly over the bowl, and absolutely never hold a child's head inside it. When sounding several bowls together, keep enough distance between them so the vibrations do not amplify each other too strongly. If anyone has a metal implant or a stainless steel joint prosthesis, please ask them in advance whether they feel comfortable near the bowl. A soft, dry or slightly damp cloth is enough for cleaning.
What you will experience
You will hear a clean, deep, long-sustained tone that fills the room after a few seconds. The C-tone stays stable, so the bowl supports calm, balanced attunement. Because of the 432 Hz tuning, many people find the tone rounder and softer than the tones of usual 440 Hz instruments. The pitch may show a deviation of around 2 Hz, which is the natural spread from manufacturing. The set arrives with the stability ring and the glass mallet, so you can try it right away.
