Some stories begin with a spark. Ours began with a diamond.

We met in Boston, at a time when our lives were in motion—our husbands were deep into their MBAs, and we were each chasing our own dreams. Mariana was launching her own jewelry brand while working at L’Oréal; I had been crafting my own for years. Jewelry wasn’t just something we loved—it was a language we both spoke fluently. Over countless conversations, ideas turned into plans, and plans turned into something bigger than either of us imagined.

After Boston, we moved to Miami, carrying with us the vision for Marai: a brand that honors the timeless allure of fine jewelry while rewriting the rules.

Diamonds should be brilliant, not controversial.

At Marai, we only use lab-grown diamonds—real, radiant, and ethically made. They carry the same fire, the same strength, the same timeless allure, but without the harm.

The future of fine jewelry is clean, and we’re here to lead the way.
