Pewter actual size: 1″ x 1/8″ diameter. This Shield of protection is a Celtic design based on the numbers 3 and 4, which enable magical powers to come into play that help provide circles of protection and other important esoteric forces to enhance well being. The central design in this work is a Quatrefoil composed of 4 circles interlocked into magical Celtic Knots. They represent the four corners of the Earth, the 4 winds, the 4 elements: earth, air, water, and fire. Most importantly these points represent the 4 angelic guardians. The quatrefoil is a symbol of good luck as in the 4-Leaf clover. One of several world symbols, this design is where the 4 realms of North, South, East, and west are joined and the 4 elemental angelic guardians bring protection to those who wear this amulet. Comes on an adjustable black cord.
