Private engagement ring design

Build the ring you actually want, not the closest thing in the case.

I’m Andrew Gonzalez. I buy and sell diamonds in the trade, and I build engagement rings for couples who would rather have the ring they keep picturing than whatever a showcase happens to hold. Sometimes that means sourcing the exact stone. Sometimes it means modifying the right setting. CAD comes in only when the ring has to be built from the idea up.

What gets decided

The plan comes before the ring.

Our first conversation turns your inspiration into real decisions: the diamond path, the setting direction, the production route, and the timing around your proposal, with the numbers in writing before anything is made.

01

A custom ring can begin several ways

Some couples know the diamond shape first. Others bring a photo, a family stone, or a setting that is almost right. My job is to translate that into decisions about diamond type, proportions, setting profile, metal, and production path, and to tell you plainly which parts are worth paying for.

Everything happens by appointment, usually on the first floor of the Jewelers Exchange downtown, so the conversation stays about the person wearing the ring instead of a tray of preset inventory.

  • Source the exact natural or lab-grown diamond, judged by eye.
  • Modify an existing setting when the foundation is close.
  • Use CAD when the ring needs to be built around the stone.
  • Plan the wedding band relationship before production.

02

The stone gets chosen in person, not off a report

Two diamonds with nearly identical grading reports can look nothing alike. Inclusion placement, transparency, and cut behavior never make it onto the paper. I reject the stones whose reports flatter them and put the honest ones in front of you, side by side, reports on the desk.

Natural and lab-grown are both on that desk if you want them to be. I hold no inventory, so I have no stone to push and no agenda about which path you choose.

03

Built for San Diego proposals

Whether the proposal is planned for the coast, a private dinner, or a family weekend, the ring has to be ready for the moment and practical for every day after it.

Most rings finish in 14–30 days. Heavy CAD work can run longer, so if your date is tight, tell me the date first. You’ll get a straight answer about what’s realistic before any deposit changes hands.

Questions couples ask before the first appointment

What should I know before starting a custom engagement ring?

You don’t need jewelry vocabulary. A photo, a preferred shape, a timeline, and a budget range are enough for me to map the path. If all you know is what you don’t like, that works too.

How do I choose the right diamond shape?

Shape changes everything: finger coverage, sparkle pattern, setting options, and how large the stone looks face-up. The useful comparison is shapes side by side in the same budget, not isolated photos. That’s a fifteen-minute conversation at the desk.

Should I choose natural or lab-grown first?

Neither, necessarily. Decide the look and the budget first, then compare both paths in the same shape and design direction. I’ll put one of each in front of you and let your own eyes settle it.

How much of the budget should go to the diamond versus the setting?

There’s no universal rule, and anyone selling you one is selling you something. A clean solitaire pushes budget into the stone; a detailed setting or matching band plan shifts it. The goal is not spending in the wrong place for the design you actually want.

How long does a custom engagement ring take?

Most rings finish in 14–30 days. CAD design, unusual stones, or revisions can take longer, and you’ll know the realistic window before committing to a proposal date.

Can a custom ring still be practical for daily wear?

It has to be. Setting height, prong or bezel protection, band width, stone security, comfort, and wedding band fit all get decided with the next fifty years in mind, not just the proposal photo.

Text Andrew the ring style you keep coming back to.

A photo, sketch, or even a rough idea is enough to start. I can usually tell you whether the smartest path is a sourced diamond, a modified setting, a CAD build, or a short call to compare options.
