An eternity necklace, sometimes called an infinity necklace, is meant to symbolize eternity, everlasting love and empowerment. An eternity necklace contains a lemniscate, a symbol which looks like the number 8 on its side.
An eternity necklace usually means something different to everyone who owns one. Some women receive them as gifts from their significant others as a symbol of undying love. Others wear them as a way to symbolize undying strength after overcoming things such as domestic violence or cancer. The infinity symbol used in the necklace might be engraved with a quote or the name of a loved one, and some often have gems attached to the symbol.
