A riff on our best-selling Dual Birthstone Ring , the Double Birthstone Stacking Ring is fully customizable. It's designed with your choice of two gemstones (one 2.5mm, one 1mm) that are bezel set in 14k gold. Pair your birthstone with a person you love, re-imagine a traditional Mother's Ring or simply choose two of your favorite stones for a design that is uniquely your own. Delicate on its own, we think she looks best when stacked with others. Available with your choice of all twelve birthstones. A staple from our Birthstone Collection . Handmade with love in Los Angeles.
