Forever Brilliant. Ethically Yours.

Our Story
We’re Leo & Nel, a husband-and-wife team who’ve dedicated our lives to jewelry design, with over two decades of artistry behind us. We’ve grown with this ever-evolving industry, worked with the finest diamonds, and mastered the craft of design, creating countless pieces that have left our customers in awe. But one thing has always bothered us: the hidden costs of the traditional diamond industry: on our planet and its people. The more we learned, the harder it became to ignore. Destroyed landscapes, exploited workers, opaque pricing…We knew there had to be a better way.
So, we set out to create something different. A brand that redefines luxury, not just in appearance, but in ethics. And that’s how Leonids was born.
Our name is inspired by the Leonid meteor shower. Just like this meteor shower, our jewelry is designed to be rare, radiant, and unforgettable. Each piece captures the essence of cosmic beauty while honoring the Earth it comes from: crafted with sustainable, 100% conflict-free lab-grown diamonds and ethically sourced recycled precious metals that shine as bright as the stars.
OUR MISSION
"We believe that luxury shouldn’t come at the cost of the planet or its people. This mission is at our core and it's in our ROOTS. We live and breathe this philosophy. And that’s how we are reimagining fine jewelry by merging beauty, ethics, and innovation to create something truly extraordinary."
Lab-Grown Diamonds
Zero mining. Zero exploitation. Every diamond is 100% conflict-free, lab-grown using renewable energy, slashing carbon footprints by 60%-70% compared to mined stones.
Recycled Gold & Silver
Every piece in our collection begins with recycled gold and platinum, giving precious materials a new life while reducing environmental impact.
Radical Transparency
Fair pricing, no hidden costs. Enjoy natural diamond quality at 40-50% less. We remove the middlemen and high markups. This makes luxury jewelry affordable for everyone.
Sustainable Packaging
We are proud to package our jewelry in materials that can be fully recycled. These materials are responsibly sourced, which helps reduce the environmental impact of each purchase.

Ethically Crafted, IGI-Graded Diamonds
We stock a collection of exceptional quality, ethically crafted diamonds, each graded by the International Gemological Institute (IGI) - one of the world’s most prestigious independent gem certification organizations.
With over 45 years of expertise and a presence in major diamond centers worldwide, IGI assesses diamonds based on the 4Cs: cut, color, clarity, and carat weight, but it is also a leader in certifying lab-grown diamonds. Our lab-grown diamonds are created using sustainable practices, and their quality is held to the highest standards, just like mined diamonds. Each piece you purchase at Leonids is backed by the trusted IGI grading system, all while protecting the planet.

Jewelry Made by Masters
We’re jewelers and a lifelong artisans who have spent over 20 years perfecting our craft. Every piece we create is a labor of love, blending time-honored techniques with modern innovation. We know this stuff inside and out, and our passion shines through in every detail—from hand-setting each lab-grown diamond to polishing the recycled gold and silver until they gleam. We don’t take it as just making jewelry; we take it as we are crafting treasures that tell a story and last a lifetime.

Jewelry as Unique as You
Your jewelry should be as unique as you are. That’s why we offer a fully customizable design experience where you call the shots. Whether you’re choosing one of our signature pieces or working with our expert team to create something completely one-of-a-kind, we’re here to bring your vision to life.
From selecting the perfect lab-grown diamond to tweaking every setting and finish, we make sure that every detail is exactly how you want it. Because when it comes to your story, nothing less than perfection will do.
