About us

Katerina Maxine is a family-owned fine jewelry house, founded over 30 years ago and rooted in the highest level of craftsmanship.

For decades, we have worked quietly behind the scenes, designing and manufacturing fine jewelry for private clients, global luxury brands, and the houses that define the industry.

As a master jeweler based in New York City, our reputation was built where precision, discretion, and artistry matter most. We have led the creation of exceptional high jewelry pieces for some of the world’s most important auction collections, while serving as a trusted custom jewelry manufacturer for leading designers and fine jewelry brands.

In many ways, we have long been the jeweler behind the jewelers.

Every piece is handcrafted in New York City, where decades of experience meet an uncompromising standard of craftsmanship. Our expertise in natural diamonds, diamond setting, and fine jewelry design reflects a deep understanding of balance, proportion, and how a diamond should truly come to life, something only developed over a lifetime at the bench.

Now, for the first time, we step forward under our own name.

Our bridal and fine jewelry collections reflect everything we have spent decades refining. Specializing in custom engagement rings and bespoke fine jewelry, each piece is thoughtfully designed and meticulously made, centered around natural diamonds of exceptional beauty. From one-of-a-kind diamond engagement rings to refined gold and diamond jewelry meant for everyday wear, every design carries a quiet strength and a distinct sense of individuality.

Beyond our collections, we offer a highly personalized custom jewelry experience, bringing any vision to life with the same level of artistry and precision trusted by the industry itself. Whether reimagining a meaningful heirloom or creating a completely custom engagement ring, each piece is approached with care, expertise, and an unwavering commitment to excellence.

Based in New York City and Miami, we serve private clients worldwide as a trusted NYC jeweler and Miami jeweler, offering rare access to true craftsmanship, where every piece begins with a story and is made to last far beyond it.

Because when something is truly well made, you don’t just see it. You feel it.
