The Southern Cross constellation, or "Crux" as it is formally known, was visible to the ancient Greeks. Throughout the centuries it has been used as a navigational aid and has played an important symbolic role in many cultures. This 1" diameter pendant displays the stars in the Southern Cross constellation, as well as neighboring stars down to magnitude 6. Being steel, the pendant will never tarnish, and is both beautiful and sturdy. It is hung from your choice of a 20" steel ball chain or an adjustable 16" to 18" silver chain.
