The Story Behind MM
I never set out to build a jewelry brand. I started designing because so much jewelry looked the same, and so much fine jewelry felt out of reach.
For twenty years, my work was finding exceptional people: leaders for the biggest names in tech, and Top Secret–cleared talent for space and national security. Today I bring that same eye to exceptional diamonds and natural gemstones. Most pieces are my own designs; others, like those in our Holiday Sale, are pieces I simply fell in love with. Either way, every stone is chosen with the same care. My original designs were once called too difficult to make, which only made me more determined to make them.
Originally from Porto, I now call South Florida home with my husband, two teens, and Pepper, our beautiful Great Dane. When we’re not working or walking Pepper, you’ll usually find us out on the boat or wandering through Europe.
This is just the beginning, and there’s more on the way, including something for the four-legged members of the family. Join our newsletter for early access to pre-sales and first looks at new collections. 🐆

A plume caught in the moment of its unfurling.
