This scolecite and quartz pendulum is nice because inherent in the scolecite is relaxation. When you use this pendulum, you can achieve a balanced and relaxed state that makes using it more effective.
If you would like more information about how to use a pendulum, go to my blog, Using a Pendulum: Basics.
Spirit Dancer will choose one of these pendulums for you, prices are per item. As a side note, I use a pendulum and your name/guides to choose the right one for you.
