The symbol associated with your sign is the water bearer, it is symbolic of the Gods nourishing the earth with life giving energies. One of the first to be called the water bearer was the Greek God Zeus in mythology.
The color of choice for Aquarius is TURQUOISE
TURQUOISE
The beautiful Turquoise is your starstone.
The name comes from the French "turquoise", which means "Turkey" as in the original localities in Persia (today Iran). Since before 4000 BC Turquoise has been used and coveted. It can be pure in color or may contain secondary minerals. If the matrix forms a pattern of interlocking polygons it is called "spider-web" turquoise.

RE: STARSTONE CONTROVERSY
There is, and always have been, a controversy over "starstones". Starstones are NOT birthstones. I give you here in these pages the stones that are called your starstones, (planet stones), which vibrates the strongest to your planet or sign, NOT to the month that you were born. I would also like it if those who think they know precisely what their stone is to go to the library and reference some good Astrology books such as 'Parkers Astrology'. Sorry for the confusion, but confusion over this topic has raged for hundreds of years.
