Custom commissions

Idea to finished piece in as little as ten days.

This is how a custom lab-grown diamond piece comes together, guided by our team from the first idea to the final polish. It is a conversation, not a checkout. A ready-to-wear collection is on the way; this page is about a custom commission.

Before we begin

Made to order, made around you.

A custom piece is designed around you from the first idea, priced once and clearly, and made by hand in our Los Angeles studio, usually in about ten days.

You stay in it the whole way. You approve the design and the stone before we start, and nothing is binding until you say so.

Share your idea

Start with the inquiry form, a call, or a studio visit, and tell us the piece you have in mind. A reference photo, a sketch, or a rough feeling is enough. The consultation is free, with no pressure and no obligation.

02 /

Review the design and stone

We turn your idea into a design and select certified diamond options to suit it. You see the design and the stone details, with one clear price, and nothing moves forward until you approve both.

03 /

We make it by hand

Your approved design is cast, set, and finished by hand in our Los Angeles studio. Nothing is sent out to anyone else. This is where the craft shows up.

Certification and final check

Your center stone comes with its independent grading report, and the finished piece is checked against the approved design under the loupe before it leaves the bench.

05 /

Delivered to you

We ship fully insured, wherever you are, or you collect it at the studio. Most custom pieces are ready in about ten days. Larger commissions take longer, and you get the honest timeline up front.

Made in Los Angeles

Every step under one roof.

From the first sketch to the final polish, your piece never leaves our studio. Designed, cast, set, and checked by the same hands, so nothing is lost in a hand-off and no corner is cut out of sight.

Pricing

Priced to the piece, once and clearly.

Because every piece is made to order, there is no fixed price list. Once we understand the design, the diamond, and the metal, our team prices the piece as one clear number before anything is made. No moving targets, and no surprises after the fact.

Expect our pricing on stones and materials to stay competitive. The craft is not where we save, and the price never moves after you approve it. A deposit starts the work, and the consultation itself is always free.

Own the piece now and spread the cost if you like, with Shop Pay, Afterpay, Klarna, or Affirm.
