You will not be able to get a reading with a multimeter while the necklace is strung on the cord. I will send a single a bead along with the necklace that you will be able to have two flat sides to get an electrical conduction reading, which will be 0.00 - 0.01
Elite Shungite Crystals are the ultimate EMF Protection crystal. Shungite is also my top pick for EMPATH PROTECTION for us sensitives. A more pure form of Shungite called Noble Shungite, or Elite Shungite, is extremely rare and has a silver-ish tint on its surface. The pure stones rarity makes it pretty expensive and also very challenging to get your hands on a piece. Its physical structure itself is almost completely carbon, leading to fewer impurities of other elements. This Elite Shungite Necklace is 19 Inches long. Bead size is 6mm
