About this piece

This wonderful Trinity Knot necklace channeled between two rows of brilliant marcasites. It comes with a sterling silver chain with a safety clasp closure. The 18″ chain passes through two loops on the back of this piece to ensure that it hangs perfectly. This well known Irish symbol is a beautiful piece of Celtic jewelry. The Trinity Knot has many meanings in many religions. This Triple Trinity is made with marcasite which contrasts beautifully with the silver and adds a sparkle to the pendant. It makes a beautiful gift for her, or a little something for yourself.

History of the Celtic Trinity

The leaf-life trinity knot, or triquetra (from the Latin 'three-cornered), was used by early Christians to represent the Holy Trinity, though the symbol has its roots in earlier pre-Christian religions, possibly existing thousands of years beforehand. Being such as versatile symbol, the triquetra has countless interpretations - the number three was an important number in Celtic symbolism, so possible meanings also include the unity of the earth/sea/sky, the three stages of life, or various triple-deities. 

The symbol came to prominence during the period of 'insular art' in the early middle ages, which combined early Christian and Celtic art. Some of its most famous incarnations are found within the artwork of the Book of Kells. It was popularized again during the Celtic Revival of the 19th Century.
