Celtic crosses symbolize a bridge to another world of higher energy and knowledge. The first Celtic cross had four equal points representing the four directions, and the four elements enclosed by a circle representing the sun. Early Celtic crosses were used to mark holy spots in pre-Christian times.

Most Celtic crosses use knots or knotwork in their design. Some of the more common Celtic cross designs include the following:

Simple Knotwork Cross - represents the unity of life and death or of belief of heaven and earth.

Triple Knot Cross - represents the interlocked levels of our physical, mental and spiritual being.

Trinity Knot Cross - represents the interlocking stages of birth, death and rebirth.

Celtic crosses are generally worn as pendants on necklaces but are also seen as earrings.
