Custom jewelry, built around your stone

Design a one-of-a-kind piece with Avi and his team. Start from a gemstone you love, a setting you like, or just an idea. You see and approve the design before anything is made.

Three ways to start

Engagement rings in Chicago

Start with a stone

Browse loose gemstones and pick the exact one. We design the piece around it.

Start with a setting

Choose a ring style first, then match it with a center stone in the ring builder.

Start with an idea

A sketch, a photo, a family stone or a feeling. Tell us about it and we'll take it from there.

How it works

Five steps, and you approve each one before we move on.

  1. Consultation

    Style, budget, timeline and who it's for. In the showroom or on video.

  2. Choose the stone

    We pull options that fit, or work with a stone you already have.

  3. Design

    Sketches and a 3D render. Revisions until it's right.

  4. Make

    Cast, set, polished and checked under magnification.

  5. Delivery

    Pick up in Chicago or receive it fully insured.

What sets the price

No surprises. You get a full quote after the design step, before anything is made.

The stone

Usually the biggest part. Type, size, color, origin and treatment all matter.

The metal

14k or 18k, yellow, white or rose gold, and how much of it the design uses.

The design

Accent stones, detailing and complexity of the setting.

When I got the piece in hand, I couldn't believe how brilliant the stones were and how stunning the piece was as a whole.
