About Marrin Costello Jewelry

STARTED WITH A BEAD KIT — NOW WE'RE HERE™ Marrin Costello is an American businesswoman + designer + brand architect. 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 luxury lifestyle brand that is sold around the globe — with jewelry at its core. THE LITTLE BLACK DRESS OF JEWELRY BRANDS™ 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, non tarnish, and rust resistant, and sustainable. As an extension of our sustainability initiative, we also now plan a tree for each item sold — yielding upward of 10,000 trees planted in just a few months. Each piece is crafted of heirloom quality, built to last a lifetime, and final assembled from our Tampa, Florida headquarters — shipped with so much love from our fabulous team to you. THE MARRIN COSTELLO® MISSION: As a dynamic lifestyle brand, our mission is simple — to strengthen confidence, spur genuine connections, and build lasting relationships through conversation pieces. We breathe our three pillars of Beauty, Excellence, and Community into each and every facet of the brand — from design to experience to content and beyond. We hope you love the collection as much as we do! xx, Marrin + Team MC Read their story
