I bought 2 devices from this seller, and they are beautiful and interesting, but they do not give off any perceivable energy. I am a very energy sensitive person, and I do not feel any energy coming from them at any distance. I bought them for the purpose of charging my water overnight, hopefully there is some benefit for water to see the geometry through clear glass and help structure water. These devices are described as energy devices with healing and spiritual properties, but they are really not. They are very overpriced jewelry. If you are interested in buying real energy healing tools, the most powerful I found so far are from photonorgone.co.uk (orgone plates/pyramids, copper tensor rings, feedback loops, acuvac etc.).
