Magic Knot was originally used during the middle ages to ward off malevolent Powers. The symbol is made from four intersections of vesica piscis shape, which represents fertility, birth, feminine sexuality and the natural force of women. The binding circle is representing a sacred or consecrated space. Magic Knot is also widely used as a modern-day symbol of protection against all types of evil. The four intersections of vesica piscis also reflect the shape of an eye, emphasized by the use of blue sapphires, which indicates spiritual protection.
