Birthstone Collection

Your birth month, your style.

Our Birthstone Collection brings a pop of color and meaning to your everyday ring. Each one is inspired by the gemstone of the month — like garnet for January, amethyst for February, and turquoise for December.

Whether you’re wearing your own birthstone, stacking your loved ones’ months, or just vibing with a color you love, these rings are all about personal expression. And because they’re made from soft, breathable silicone, they’re as comfy as they are meaningful.

Choose from our signature Arc, Dual Layer, and Stacklet ring styles — and make it your own with custom engraving inside.

Meaningful, giftable, and made to move with you.
