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!

Our customers LOVE Marrin Castello jewelry!! I’ve been ordering for years and it just keeps getting better. Marrin does a great job at designing unique pieces that are on trend but not the same design you keep seeing that is played out. Highly recommend!
