I have a twelve-sided Vogel, but the proportions lean toward thick and short. This particular wand felt right for me. It is carved from clear quartz containing silver veils. Twelve contains three and four. Although four resonates most strongly with me, three is powerful as well. Twelve relates to the structure of this universe and the state of our consciousness in relation to our home.
You can obtain technically exact Vogels, to Vogel's specificifications, precisely cut, but they will cost a lot. I've played with a number of those and if one has the money, why not? They have a unique feel and energy. However, the garden variety such as the one sitting on my lap work as well for me.
A friend and I took turns holding the same Vogel and we unexpectedly opened to each other energetically and telepathically. It was surprising how quickly this happened and strong this was! I would look up Vogel's work and read about the uses he explored and experimented with, in addition to his theories, if you are interested. I'm fascinated, just swamped with all the remembering and learning with the stones. Thanks for the reminder.
