Custom Design

One-of-a-Kind, Not One of Many

custom yellow gold halo engagement ring

All of Ada’s bridal pieces are fully custom, made-to-order, and are never mass-produced. To start, most clients take inspiration from one of our existing Collection Pieces, modifying the design to meet their vision. Your concierge is with you every step of the way to ensure a gorgeous, timeless ring.

If you’d prefer to design from a photograph or verbal instruction, we can start with a blank canvas. All of our jewelry is designed in computer aided design (CAD).

A 20% non-refundable deposit is required to reserve a diamond or start a custom design. You will receive an estimate for your custom piece before placing a deposit.

How It Works

Custom design follows two basic steps: computer aided design (CAD) and photorealistic renderings.


CAD will show overly thick metal and extra long prongs that are cut and polished during setting. You may make as many modifications to the design as you’d like. Most clients are in and out of CAD in 3-7 days.


Photorealistic renderings are 2D representations of your ring, like the kind you see all over our website. Your renderings are of your diamond in your ring in your size. They are not “sample” images.

Proposal Settings

Not sure what your sweetheart desires? Set your diamond in a simple solitaire, propose, then return with your loved one to design her dream ring forever. You will receive full credit from the original setting toward a new setting without a re-setting fee.
