Silver Celtic Rings
A silver Celtic ring with a Triquetra, Celtic Knot symbol.
This Celtic spiral knot has been said to be a depiction of eternal life and the reincarnation of the spirit throughout infinity. Some historians have also suggested that the three-fold symbol represents the three major elements; earth, water, and fire. Whatever narrative you adopt, it is undeniable that the Triquetra inspires a feeling of renewal/rebirth.
