CARAT FREEDOM
The Diamond You Wanted.
Traditional retail pricing does more than increase the cost. It limits your choices. By working directly with our manufacturing partners, Leonids removes unnecessary markups so you can invest where it matters most: a larger diamond, exceptional craftsmanship, and a ring you truly love. We call it Carat Freedom.

EXCEPTIONAL MATERIALS
Made To Last.
Every Leonids piece begins with carefully selected lab-grown diamonds chosen for exceptional brilliance and beauty. We use only D and E color diamonds with VVS clarity, paired with recycled precious metals including 10k, 14k, and 18k gold, as well as platinum. Ethically created and expertly crafted, our materials are chosen not only for how they look today, but for how they will be worn and loved for years to come.

MADE TO ORDER
Crafted For One Story.
Your story. Every Leonids piece is made to order and crafted specifically for your purchase. From casting and stone setting to polishing and final inspection, each piece is created by skilled artisans with extraordinary attention to detail. Because something this meaningful should never feel mass-produced.

Frequently Asked Questions

  • Yes! Lab-grown diamonds are chemically, physically, optically identical to natural diamonds. They're just created ethically above ground.

  • Carat Freedom is our approach to diamond pricing. By working factory-direct, we remove traditional retail markups so more of your budget goes into the diamond itself, allowing you to choose larger, higher-quality stones without compromising standards.

  • No. Leonids works exclusively with lab-grown diamonds in VVS clarity and D–E color. Carat Freedom comes from removing middlemen, not lowering material or craftsmanship standards.
