Dawn Del Russo from Live The Glamour recently sat down with Marrin for an inspiring, in-depth conversation about all things entrepreneurship, jewelry design, and building a brand from the ground up.
What began with a childhood bead kit gifted at age seven has evolved into a global jewelry brand recognized for timeless style and intentional design. In the interview, Marrin shared her journey—from selling handmade pieces at craft fairs to leading a company stocked in over 400 stores nationwide.
“Jewelry happened to me—I didn’t choose jewelry, jewelry chose me.”
– Marrin Costello
The two talked about the importance of evolving with your brand, staying true to your aesthetic, and why stainless steel became the foundation for the MC collection. Marrin also spoke about her best-selling pieces like the Gabriella Chain and Cyrus Choker, as well as her commitment to offering high-quality, multi-functional designs that elevate everyday style.
Beyond jewelry, Marrin discussed her mission to empower other creatives through business consulting and her podcast Marrin Costello Radio, where she highlights trailblazers across industries.
This conversation is a must-watch for anyone dreaming of turning their passion into a purpose-driven brand.
