Shungite Palmstones

Black, lustrous Shungite is a mineraloid of carbon, mined in Russia.  It has long been known for its antibacterial properties, and more recently for its ability to absorb electromagnetic radiation. These polished stones fit nicely in your hand, and make a nice touchstone.

Palmstones are about 5 x 3 cm (2 x 1.25") in size.
