This listing is for a single shungite tumble stone in your chosen size option.
Several scientific studies speak of potential health risks from cell phones, smart meters, and electrical appliances resulting from the electromagnetic fields (EMFs) they emit. Background technologies like wireless routers, bluetooth, and other wireless systems give off radiation in the low-gigahertz frequency range that may cause harm to the nervous system or cognitive function when exposed over long durations of time. Studies have also shown that shungite has a shielding effect, reducing the severity of damage produced by high-frequency electromagnetic radiation.
Tumble stones are polished and made from Type 3 regular shungite from Karelia, Russia. Type 3 shungite contains up to 50% of carbon. It has deep gray or black color, small pyrite infusions are possible.
Note: shungite has been shown to be be more effective with close proximity to devices, increasing range of effectiveness with larger pieces and for higher-grade specimens, as aborption ability varies based on mineral inclusions and microporosity of a stone's carbon molecules (e.g., Type 1 Elite Shungite with higher carbon make-up)
