A strong association with the sea makes the aquamarine a natural match for Aquarius the sign of the water bearer. Aquarius is known as a visionary sign, and the aquamarines properties energise visionary psychic powers. Many an Aquarian knows the frustration of having ingenious ideas and waiting years, yes even decades, before the ideas gain popular understanding or appreciation.
Aquarians tend to get so absorbed in their projects they've over the years gained the reputation of being the mad scientists or absent minded professors of the zodiac. The protective powers of the aquamarine can keep the Aquarian out of dangers way as he or she wanders around lost in thought.
