Celtic Zodiac Swan Pendant (September 2nd – September 29th). An elegant Celtic swan features prominently in this pendant. Its feathers and beak are very finely detailed. A Celtic infinity knot representing the unending cycle of life, stands beneath the graceful creature. Celtic mythology associated the swan with life and virtue. Those born under the swan zodiac are calm, honourable, sensitive, critical and dedicated. Impulsive behaviour is quite rare in these people, they prefer to analyse all the miniscule facts first. Calm by nature, they will however become truly ferocious if their own are threatened in some way.
