Shungite Palmstone - EMF protection
Shungite appears to be a smooth black stone, however it is actually fossilized coal with high Carbon content (around 98% is carbon). Shugnite effectively filters Electro Magnetic Fields (EMF) and is currently being widely employed in water purification devices and in cellphone covers. Neat stuff.
Here we have lovely genuine Shungite palmstones measuring 2 1/2 x 1 1/2 inches and weighing just below 2oz. It's a very light material that protects you against electromagnetism.
