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.
Rose Quartz protects against intrusion and others anger or spite, nightmares, and is good for fertility magick. It can also be used in peace magick for war torn areas of the earth.
