Our quartz crystal singing bowls have a beautiful translucent white surface, they are produced with pure quartz crystals of the highest quality in TOPFUND factory. Our crystal singing bowls and crystal singing bowl set are made from the purest quartz crystals. They are fired at extreme high temperatures until they fuse, forming quartz glass. Some formations may occur during the firing process including bubbles, lines and spots. These features are perfectly natural and do not affect the sound or performance of the bowl in any way. TOPFUND only produces the highest quality crystal singing bowls and accessories with the highest quality standards in the world. We have sorted our crystal singing bowls by both sizes and by the dominant note produced by the singing bowl. While larger singing bowls tend to produce notes from deeper octaves, all singing bowl meditation size categories contain a variety of possible notes and some notes are more common in certain size categories. We are constantly updating our crystal singing bowls and crystal singing bowl set inventory so please subscribe to our store to check for note and size availability. The crystal singing bowl is a high-quality fragile instrument, but with proper handling, it can remain beautiful and viable for a lifetime. Always handle your crystal singing bowl with the utmost care and take special precautions while transporting or storing it. It is also imperative that appropriate strikers, rubber mallets, and O-rings are used when your crystal singing bowl is played. We suggest that the crystal singing bowls are always played at a minimum of 10 inches from a person’s head. Also, avoid playing these crystal bowls within 10 inches of each other as their intense vibrations can lead to shattering or breakage. Every TOPFUND singing bowl and crystal singing bowl set come with professional safe carrying packages, suede striker or rubber mallet and O-ring for free for sound healings chakra meditation and yoga practice.
