Our Story

Fine Jewelry
Inspired by Color.

Lab-grown color diamond jewelry, backed by more than 50 years of combined industry experience.

Why We Created Lab Diamonds of America

A New Way to Experience Fine Jewelry.

Lab Diamonds of America was founded by Alex and Jill Muller on a shared vision: fine jewelry should feel personal, expressive, and part of the life you live every day.

After decades working throughout the global diamond and jewelry industry, we saw firsthand the beauty, craftsmanship, and meaning that fine jewelry can hold. We also saw an opportunity to make extraordinary color, thoughtful design, and lasting quality available to more people.

Exceptional jewelry should be enjoyed, celebrated, and lived in.

Inspired by Color

Color Is at the Heart of Our Story.

Our passion for color began decades ago in the world of natural fancy color diamonds. Today, we specialize in lab-grown color diamond jewelry, with a deep appreciation for the extraordinary beauty of yellow, pink, blue, and other rare colored diamonds.

We are launching with yellow and pink diamond jewelry, with plans to explore more colors as our collections grow. White diamonds will remain an important part of our designs, bringing timeless brilliance and balance to the color at the heart of our brand.

As technology evolved, new possibilities emerged. Colors that were once available only to a select few could now be enjoyed by a broader audience through beautifully crafted fine jewelry.

Lab-grown color diamonds do not replace our appreciation for natural diamonds. Instead, they open the door to a new way of experiencing color, creativity, and personal expression.

Wear. Layer. Collect.

We believe jewelry should evolve with you. Our pieces are thoughtfully designed to complement one another, allowing you to build a collection over time—beginning with diamond studs, adding a necklace, layering bracelets, or creating a personal ring stack.

Luxury is not only about special occasions. It is the jewelry you reach for every day: the pieces that travel with you, celebrate with you, and become part of your story.

A Love Story Built on Diamonds

One Dance.
One Run.
A Second Chance.
A Shared Vision.

Long before Lab Diamonds of America was founded, Alex and Jill’s story began in Las Vegas during the annual JCK Jewelry Show—not in a showroom, but on a dance floor. What began with one dance and a brief connection eventually led them back to their busy lives in New York.

Years later, without knowing the other had registered, they met again at the 2013 Jewelers for Children Charity Run during JCK. A shared passion for running and giving back gave them an unexpected second chance.

Their friendship grew into a lifelong partnership grounded in shared values, mutual respect, and love for both family and the industry that introduced them. Today, Alex and Jill are proud parents to their daughter Isa and are building Lab Diamonds of America together, combining more than five decades of experience with a shared belief in jewelry made to be enjoyed every day.
