This is the ring 25-year-old me really wanted. It fills that hole — and now the ring I wear can match how I feel about my relationship.

The Atelier

The JbC Custom Design Process

From your first message to the moment you hold it — every step guided by Gabrielle personally.

01 The Conversation

Tell Gabrielle what you're imagining: the stone, the style, your date, and a comfortable budget. She replies personally within two business days.

02 The Stone

Gabrielle searches natural, lab-grown, and colored stones for you and sends back two or three worth seeing, each filmed by hand.

03 The Design

A CAD model and renders built around your stone. Revisions are included, and nothing is cast until you approve.

04 The Making

Handcrafted in the US and inspected at every stage, usually 4–6 weeks after you approve the design.

05 Delivery & Aftercare

Fully insured delivery with documentation, plus ongoing support for resizing or future changes.

Every piece begins with a conversation

Tell Gabrielle what you have in mind — a stone you've inherited, a design you've been sketching for years, or nothing more than a feeling. She reads every message personally and replies within two business days.

The curator behind the vault

Hi, I'm Gabrielle.

I started Jewelry by Cleo with one belief: the most meaningful pieces in your life should come with complete transparency — on the stone, the craft, and the price. I personally curate every diamond, looking for that specific watery sparkle a lab report can't describe. If I wouldn't wear it on my own hand, it doesn't make it into the shop. Period.
