Circle of eternity

The wedding ring is SUPPOSED to be symbolic .

A CIRCLE: this was the symbol of eternity for the Egyptians as well as many other ancient cultures. It had no beginning and no end, like TIME. It returned to itself, like LIFE; and the shape was worshiped in the form of the Sun and the Moon.

THE HOLE in the center of the ring is not just space either; it is important in its own right as the symbol of the GATEWAY, or DOOR; leading to things and events both known and unknown - hence "FOR BETTER OR FOR WORSE"

SELAH....
