Our Craft

Twin founders. One standard.

Founded by identical twins in New York's Diamond District, Ancona pairs two trained eyes at the bench — one shared standard for proportion, polish, and everyday wear.

Designed together. Finished by hand. Made to be worn, gifted, and kept.

We don't sell jewelry. We hand someone the piece they'll be wearing in every photograph that matters. — The Ancona Family
Our Story

The Process

From sketch to signature piece

Every Ancona piece passes through the same four hands-on stages.

  1. Design

    We start from a drawing and the customer's intent — a classic to live in, or a one-of-one to remember.

  2. Cast & Form

    Gold is cast and chains are built link by link in our own workshop.

  3. Set & Finish

    Stones are set by hand and each surface is polished until the light sits right.

  4. Inspect & Present

    Every piece is checked, cleaned, and packaged ready to give.
