The description: You can be sure that this pendulum will help you attain a clear mind and obtain a compassionate, loving answer to any questions you may ask.
My home inspector had a quartz pendulum with a big chip broken out of it (apparently that doesn't matter.) And the way it works is, you hold the chain between your thumb and finger, and ask the pendulum a yes or no question. Usually, yes is away and towards you, and no is side to side. I was fascinated by this. Now you can't just order something online or even go to the local new age bookstore to buy one. You have to go to Las Vegas, NM, to buy one from a guy who makes them. And the pendulum chooses you, not the other way around. The way that works is you use a necklace first, and then you take it with you, and then you ask the necklace to help you find your pendulum.
I don't have too many necklaces here, but I do have one that has a hanging thing on a chain, so I tried it at home. But it didn't seem to do much. Then I looked online and discovered that not only does the pendulum choose you, but you have to train it first. I won't go into the process, which is quite detailed. You can look it up under "dowsing." It's just like when people find water with the forked stick. How does it work? I don't know. It might be similar to the Magic Eightball. I find that to be a great source of answers: "ask again later."
