This necklace is made from solid natural shungite. It weighs a total of 181 ctw. The large shungite stone at center measures approximately 28mm by 23mm. All the shungite stones (except for the round shiny beads) are a matte black with some silvery-gold veining. There is an extension chain made of sterling that allows the necklace to adjust from 18 to 20 inches. The sterling is rhodium plated which will prevent tarnishing. This necklace is gorgeous! I think you will love it.
Shungite is said to kill bacteria/viruses, purify water, reduce stress and inflammation, shield electromagnetic fields and when infused with water, it will also ease some physical ailments.
