Gemstones can help you in increasing your concentration and connecting you with your inner conscious. Some gemstones are believed to have healing powers within themselves. They help us seek answers to certain questions by picking on subtle vibrations. They do so by moving in the direction of invisible energy around us. Holding the pendulum over all the seven chakras of the body helps in revealing the imbalance and energy blocks in the chakras. Pendulum, body suspended from a fixed point so that it can swing back and forth under the influence of gravity. Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant.
