It is Pan Chang knot and means Endless in Chinese. It represents cycle of life; birth, death and reborn. One of the most basic concepts of Buddhism is cycle of life, it will never ends. As one of the eight Buddhist treasure, it also represents mysteries of the Universe and also known as mystic knot. One of the garnet energies is 'Love'.
I used garnet chips and endless knots in this necklace to tell about 'Endless love'. Love will be never ended in life of cycle and it will be mystery.
