Kings Chamber plate can be used together with the Base for Ceramic Pyramid and Ceramic Pyramid to charge/activate/open gemstones, when white pyramid is pointed north with 2 parallel sides. I don't think the base or even the KC Plate is a necessity. Tests to be made. The Pyramid in combination with the Kinds chamber plate seems to work. No guarantees from my side, only sharing personal experiences. Model can be downloaded freely. I don't charge a personal fee for modeling work. If you wish additional changes I might be able to help you out. For questions, rewards, remarks, feedback, you can contact me @ mjcbakker@hotmail.com.
