About Marrin Costello

Marrin Costello is CEO and founder of Marrin Costello Jewelry. Her career as a creative began at age seven, after receiving a bead kit for Christmas. Less than a decade later, a childhood hobby has transformed into a global jewelry and accessories brand. The collection now features over 300 unique, layer-able, easily digestible styles — all available in both gold and silver. Each piece is hypoallergenic, water resistant, and non tarnish. We hope you love the collection as much as we do! Read their story
