After 15 years designing and creating in Los Angeles, Marrin moved the business to Tampa in 2021. Marrin fell in love with Tampa’s vibrant and passionate local community. She knew she had found the perfect home for herself and the brand.

When Marrin had the opportunity to take over a longstanding retail space that had been a pillar in the Tampa retail scene for 20+ years, she knew it was an opportunity she couldn’t pass up. Marrin Costello Jewelry opened their first brick and mortar flagship store in the Palma Ceia neighborhood of Tampa, Florida in October 2023.

As an active member of the Tampa community, Marrin created a space where people could shop for jewelry and celebrate the community. The store regularly hosts events in partnership with other local brands, philanthropies, and organizations.
