Two Women with a passion for jewelry

Let Us Tell Your Unique Story

With a passion for custom designs that transcend trends, we understand that jewelry is more than an accessory – it’s a piece of your story, a statement that echoes through generations

Our Story

After more than 25 years in the wholesale corporate side of the jewelry business, we were both looking to do something else. We had only ever met one time when a mutual friend connected us. As soon as
we met, we felt that “click” and knew we had to join forces.

Our first venture was a B2B consulting firm. Over the next year we found ourselves gravitating towards working directly with customers, utilizing our vast knowledge and experience. Our vision was to reimagine the jewelry experience as a concierge service in an atelier setting … and 21C Designs was born.

Jaime Polk

Managing Partner

Business is in my blood almost as much as jewelry. My entire career has been in the jewelry industry where I was a successful senior sales, management and business executive for several fine jewelry brands including Scott Kay, Karl Lagerfeld, Frederick Goldman and Triton. I worked with all of the big jewelry retailers, national companies and independent jewelers where I learned the “trade”, especially the bridal business.

founding 21C, I have become a licensed independent appraiser, studying with the Gemological Institute of America as well as the National Association of Jewelry

My jewelry journey continues and grows as well as my jewelry passion as a collector, appraiser and business partner. “Work” has never been so much

Katherine Rosenberg-Pineau

Managing Partner

I have always loved designing jewelry, pursuing this exciting field with a passion since I was ten years old. In my early years, I started on the bench, studying and practicing through high school and college at Boston University, where I pursued a degree in metalsmithing from the Program in Artistry. That solid foundation in bench skills has been invaluable as my career turned towards product development.

After a stint in retail, where I worked as a buyer and a general manager, gaining valuable insight into the issues and business of retail operations, I began a long and successful career in jewelry design and development working for some of the giants in the industry. Early in my career I headed up gemstone design and development for Town and Country Fine Jewelry. For almost ten years I led Hearts on Fire as their head designer launching their fine jewelry line, and helping the company grow from a small specialty diamond vendor into a leading global jewelry brand.

Most recently I have been an industry leader at Leo Schachter overseeing all the design and development for their jewelry divisions and working with key strategic accounts. Founding 21C Designs is a culmination of a lifetime of experience and the exciting next step of my jewelry journey.
