The Triquetra is an ancient Celtic symbol that speaks of the power of three in all things: earth, sea, and sky, birth, death, and rebirth, and the maiden, mother, and crone aspects of the Goddess, as well as past, present, and future. It is one of the simplest, yet most profound, of the various Celtic Knots. This flawlessly designed Triquetra necklace with gemstone chain by Peter Stone's finest craftsmen is an eloquent testament to the triplicities surrounding us.
