Our Process

At Gemelli Diamonds, we understand that jewelry is the ultimate of personal expressions.

It’s why all of our designs exude exceptional quality, with painstaking attention to the smallest detail. Gemelli Diamonds uses only the finest precious metals and gemstones in each exquisite design—from the most delicate heirloom ring to the boldest statement piece—and all are created and hand-finished right here in New York.

We complement this careful craftsmanship and distinctive design with exemplary service. The custom jewelry design process consists of a few steps.

Consultation: First, we’ll set up a consultation to learn exactly what you are looking for. Then we will provide design drafts of the jewelry we are designing. Once approved, we move forward with producing your one of a kind piece.

Production: Our technology allows you to see your custom-designed jewelry before we cast it. We’ll listen closely to your ideas and seek out the details, features, and meaning you want to incorporate into your one-of-a-kind piece of jewelry.

Approval: Then we can show you a realistic 3-D computer image of what you may have previously seen only in your mind’s eye. Our design process allows you to fine-tune your ideas so we can deliver exactly what you envision.
