Triquetra necklace

A triquetra is an ancient symbol that consists of three overlapping and interconnected arcs, sometimes known as a Vesica Pisces shape, that creates a tri-pointed symbol. Essentially, the symbol resembles a three-cornered knot, as all internal arcs look as though there is no beginning or end

The symbol is also sometimes used by Wiccans, White Witches, and some New Agers to symbolise the Triple Goddess, or as a protective symbol.
