Also known as a trefoil knot, or a triquetra, this iconic symbol has three interconnected “leaves” making a form that can't be untied. Given this elemental form, this design has been adopted by many different groups and cultures through time including the Celts, Irish Christians, Pagans and even modern day TV producers!
Unsurprisingly this has lead to multiple meanings that have evolved through time. But in modern day Ireland, the Trinity or Lovers Knot is a traditional symbol that sweethearts exchange in jewelry to show their love and devotion.
