Donuts are wonderful to wear on different colored leather straps or - very classy - on silver and silver gold plated donut holders.
Shungite (stab.) consists of up to 95% carbon.
Origin: Eastern Finland and Russia (Karelia, Shunga region)
Size of the shungite donuts: 4cm
Schungite supports the balancing of our inner contradictions and is therefore often worn as jewelry.
