What We Love Catbird presents our debut line of engagement rings. The Swans are elegantly modern - instant heirloom engagement rings with classic lines and proportions. Each ring couples flawlessly with a multitude of wedding bands; shape shifting in mood and era depending upon the pairing. Deceptively strong, with our signature delicate proportions. Made to last a lifetime, the collection is set and hand-finished in our Williamsburg, Brooklyn studio by our expert team of in-house jewelers. View all of our Swans here.
