I for one can NOT Hold a Quartz Stone Of any kind without it wreaking Havoc on my Senses, I know of people who can Charm the Heck out of these energies, but I; myself, Cannot. People Who can hold the Quartz and receive; channel, the energy it possess or the energy that runs through it are Freaking Amazing to me, I have met Instant Travellers, Dream Walkers, Shape shifters, Light Workers, all with the ability to use this stones to work the power that is amplified several times over. I go to hold one and my hand cramps up, some get headaches other instantly shatter the crystal just by getting to close to it. People that Can Use this power of the crystals Amaze Me, There are many in this world but few I've ever met that were honestly using the crystal to it's full potential. The dimensions out there are many, What is it you can tune in to? This crystal is approx 2inches in length, I may be off a few centimeters either way. The chain makes the pendulum approx 6-7 inches in length The Swing Is Awesome, I've seen this pendulum used, but it was not used by me. My husband is an electrician,,,,,,,ENUFF SAID. Love and Respect it's power and your ablitity to know when to stop.
