Despite my initial reservations, I have become a great fan of working with these crystalline beings and feel they can make very special working pieces, as long as they are used with respect, integrity and honesty. I don't feel that you have to have an enormous specimen for them to be effective, but I do feel that the quality of the workmanship and the energy put into their creation IS important to a large degree. This is one reason why we have now decided to offer some more expensive (but more detailed) skulls, as well as some of the more commonplace mass produced items. Therefore most of the larger skulls we now offer come from Raven in the USA. For those in the know he is acknowledged to be "The Skullmaster", and he and his team are renowned all over the world for the quality and energy of their work. All his skulls are hand-carved in intricate detail and hand finished / polished, and you know you are seeing the results of very skilful work as soon as you see them. There is more information about our own experiences with Crystal Skulls (we are Keepers for 3 "human" and 4 "dragon" skulls) on our Lightworkers website (follow links from the main / home pages).
