These Crystal pendulums are 18x41mm with a 7" Silver Plated Brass chain and a 6mm round matching bead.  A lobster claw attached to the pendulum crystal, so you can switch them out if needed. Pendulums are influence by gravity and are often used for spiritual healing or inner growth.  They are used to answer questions, receive guidance, awareness and understanding.  Use a gemstone crystal pendulum to gain clarity or a better understanding when making decisions. 
 
Pendulums swing in vertical straight lines, horizontal straight lines, and in circular movements. This can be done side-by-side, front and back, clockwise, counterclockwise, in an elliptical motion, or even in a bobbing movement up and down, which often indicates a strong affirmative action. 
 
Pendulums can be used alone or with a pendulum board.
Before you begin with your new pendulum:
Assign each directional swing a "response" by first asking the pendulum to show you what certain responses look like. For example, start off by asking, "What does a NO look like?" and subsequently, "What does a YES look like?" Posing these questions to your pendulum will help define directional swings, which must happen before advancing to more challenging questions.
 
Pendulum Response Examples:
Vertical swing signifies NO
Horizontal swing signifies YES
Circular movement signifies NEUTRAL
