Marrin Costello is a businesswoman, designer, and brand architect. Her career as a creative began at age seven when a bead kit ignited a passion for jewelry design. Over the past two decades, this childhood hobby has transformed into a global luxury lifestyle brand with jewelry at its core. 

After Costello’s collection was featured on American Idol, a business was born. Her accessories blend practicality with high fashion, always having quality in mind. Each piece is hypoallergenic, non-tarnish, and water resistant, seamlessly transitioning from working out to formal events and everything in between.

“At the heart of my brand is a mission to empower women to feel fearless, fabulous, and authentically themselves,” says Costello. 

In addition to building her eponymous jewelry brand, Costello is also passionate about supporting other entrepreneurs through business consulting and a weekly entrepreneurial-centered podcast, titled Marrin Costello Radio. What’s more, giving back to the community is essential to Costello, as she mentors young women in the Tampa community and donates a portion of each jewelry sale to reforestation and ocean cleanup sustainability initiatives.
