This rhodium brooch has a stunning silver color, and takes the shape of a traditional trinity knot, a Celtic icon that traditionally had religious significance and has come to represent everything from eternity to unity. The simple, sleek design of this brooch is timeless, and it's the perfect way to add a little bit of "Ireland" to your everyday look. Pin it to your favorite Irish-knit sweater or wool jacket.
