Thank you for viewing! This is a shungite pendant imported from Russia. It has a 2.5 cm circle within a 5 cm circle. *Please note that shungite is a mineral made of carbon, so it will initially appear black. This will come off when washed or wiped.* ❥❥❥❥❥❥❥❥❥❥❥❥❥❥❥❥❥❥❥❥❥❥❥ Shungite is said to have the power to protect the body from harmful influences and to purify the mind, absorbing negative energy such as external stress, alleviating physical and mental pain, and enhancing self-healing and immunity. It is also recommended as a 5G countermeasure. It is said to be beneficial to wear as a bracelet, necklace, or earrings because it absorbs harmful electromagnetic waves emitted from many electrical appliances such as TVs, computers, mobile phones, and microwave ovens. I have other shungite items for sale, so please take a look. I will deduct the shipping cost for combined purchases, so please let me know in the comments.
