Pisces are born between 2/20 – 3/20, generally the coldest time of year. The Pisces is exceptional due to its ability to adapt to the harshest of conditions. It inherits this magical ability from being the last sign of the Zodiac, as it incorporates aspects from every sign that precedes it. Symbolized by The Fish, it can seamlessly swim against any current, but too much difficulty can take its toll on the Pisces. Which is why Amethyst is the optimal stone for this sign.
