All pendulums vary in size and color.
Pendulum divination is a very simple form of divination that relies heavily on yes/no answers to questions about things that are and things that may come to pass. A pendulum of some sort is tied to a string or chain and held in one hand. As the question is asked, the answer comes in the form of the pendulum swinging north/south, east/west, or in circles of some sort. Mats or predeterminded directions are used for the yes/no validation.
Smoky quartz is used to protect against all forms of bad luck and to enhance energy flow through the hands. It increases creativity and intuition and transforms depression and pessimistic thought into joy and optimism.
