Approx. 2" Size. Kindly note that since these are all handcrafted items there always exists minor deviations in size and color. However, the Healing Qualities and Metaphysical Properties will be THE BEST. Crystal bowls have been used in healing modalities since the 1980's. While some people speculate on the use of crystal singing bowls in ancient cultures, I am aware of no direct evidence of their use. However, interestingly enough, in a merger of new and ancient technologies, the computer industry made very high quality, pure silicon quartz crystal bowls utilized to grow pure silicon chips for their computers. If the bowls were not precise enough, they were thrown out. Apparently someone on the way to the trash bin discovered they have incredible pure sounds, also, and decided to stop discarding them! This birthed the singing crystal bowl industry. Since this time, they have become a vehicle of enormous potential for those working with sounds in both ancient and new healing technologies. Much like the ancient Tibetan Bowls, the crystal bowls can be used as sound tools. Coupling awareness and intent in their use can demonstrably increase their effectiveness. By simply listening to the rich, pure, vibrant tone of a bowl, most sound recipients find them deeply relaxing, rejuvenating, even stirring of deep emotions and states of well being. By utilizing awareness techniques, a practitioner can guide the recipient into states of clarity, balancing of chakra centers, and much more. They can be used to transport the recipient into deep meditative states, even shamanic journeys into other dimensional states, or, realms of wisdom and understanding.IMAGE IS JUST A REFERENCE.
