Pisces' astrological gem is the AQUAMARINE.

Aquamarine is a member of the same family of stones as the emerald (the "beryl" family). Meaning sea water, "aquamarine" is so-called because of its distinctive color that is just like the ocean. Also like the ocean, this stone has a range of colors, from very light to medium blue.

The aquamarine is the perfect stone to represent the sign of Pisces, which is also associated with water and deep thoughts. Aquamarine is also very durable, just like the Pisces, who can seem wishy-washy but is blessed with a strong heart and great loyalty.

It has long been believed that the aquamarine has a healing effect on couples in love. Its power to help sweethearts work out their differences and ensure a long and happy relationship makes it a great anniversary gift.

If a Pisces dreams of aquamarine, it means that they will soon meet new friends. Aquamarine has also been said to protect the wearer against the wiles of the devil.

Aquamarines in Legend:
Since ancient times, the aquamarine has symbolized safety at sea. Legend has it that this stone was a treasure of the mermaids. In the 4th Century BC, Greek sailors wore aquamarine for protection, believing that it made them fearless and protected them from adversaries as sea, especially if the stone was engraved with Poseidon on a chariot.
