Premium Lab Diamond Jewelry / Los Angeles
We design and hand-set custom fine jewelry around large lab diamonds, made to order in Los Angeles. One piece for one person, shaped around the way light moves.
The Studio
The artists behind 100 Carats bring years of high-level craftsmanship to every piece we make: lab-grown stones, hand-selected, cut large, and set one at a time at our own bench.
Every piece is made to order, for one person. You bring the idea. We make it real.
Why lab-grown
A lab-grown diamond is pure carbon, with the same hardness and the same fire, grown in weeks instead of ages. Because the stone is grown, we can go larger and cleaner, and shape the design around the diamond rather than the other way around.
And because every piece is made to order, the stone, the metal, and the setting are yours to call.
Worn for how you live
Not made for a vault. Made for real days and real nights, dressed up or down, wherever you are headed.

Made for All
Every piece is sized, weighted, and finished around the person it is made for. Different lives, different styles, the same care carried into each one.
Grand statement pieces
For the grand commissions: our largest center stones, one-of-one designs, and the finishing usually kept for the front row. Show us the occasion, and we'll make the piece that carries it.
