Oval Solitaire
A graceful oval center stone with clean metal, generous light, and a shape that feels romantic without becoming ornate.

How most rings start: a text.
Why couples trust Andrew
Not inventory. Inspiration.
Everything starts with the stone. These are here so you can point at what she’d love, whether that’s something simple or something with more going on, and the ring gets built from there: your diamond, her hand, your number.
What custom actually means
A custom ring does not have to be complicated. The work is deciding what needs to be selected, what can be modified, and what must be built.
Compare natural and lab-grown diamonds by shape, face-up appearance, proportions, origin, and budget fit. By eye, not just by report.
Start from a strong foundation when it exists, then adjust prongs, profile, metal, side detail, or band fit.
Use CAD when the right setting is not available or the ring needs a made-to-fit side view, basket, or stone arrangement.


About Andrew
Jewelry is my family’s business, and it still is: my son Ezra runs our marketing and everything online while I handle the diamonds. I’ve owned and managed stores, my own and my family’s, and these days most of my work is wholesale: buying and selling diamonds and gold, week in and week out. I never needed a storefront, because the work comes to me instead, from jewelers who need a stone found, and from couples someone sent my way.
You reach me the same way they do: directly. Most people start with a call: what she likes, the shape, how she actually wears jewelry, and the range you have in mind. From there I write up a proposal that spells out exactly what we’re building. Only then do I go looking: the stone first, then the setting, and a straight answer about whether custom is even the right path for what you want.
Nothing sits in a case waiting for you. Every stone I show you was found for your ring, in your shape and your range, after we agreed on the plan. On any given day you’ll see me moving between jewelers, picking up gold, checking stones, and calling in favors to keep a ring on schedule. When I say I live inside this business, I mean it literally.
What I love most is building custom pieces, engagement rings above all. I proposed to my wife with a ring I made. I built my daughter’s engagement ring. I’m building my son’s right now. You won’t find a photo of any of them here, and that’s deliberate: what I make for you stays yours, not a template for somebody’s mass production.

What the paper won’t tell you
Two stones can carry nearly identical grading reports and look nothing alike in person. Mass sellers profit from that gap. I built a career inside it. It’s why I earned the GIA Applied Jewelry Professional credential instead of trusting paperwork: the training is in reading exactly what a report leaves out.
A flaw tucked near the stone's edge disappears under a prong forever. The identical flaw sitting dead center catches your eye every day. Both carry the same clarity grade.
A hazy stone can carry beautiful grades and still look like a window that needs cleaning. Transparency appears nowhere on the report. You find out by looking.
Cut is graded on round stones only. The ovals, cushions, and pears everyone is saving photos of? How bright they are, how big they look, how much weight is buried underneath: graded by nobody.


Where the good stones go
Cutters and brokers show their best stones to private jewelers first, because we’re shopping for one diamond for one specific ring. A mass retailer is filling a shelf: the margin is in volume, not selection.
Reports first, then the imagery and video behind them, before a stone earns a second look.
The finalists come to my desk so I can check each one for haze, where the flaw sits, and how it actually handles light.
What an auction, a bulk broker, or a social-media shop is actually selling. The report is the beginning of the conversation, not the end of it.
The open-book offer
The big diamond websites say no storefronts keep their prices low. Then they spend millions marketing the brand and pay thousands of employees to sell you a stone off a report, sight unseen. The chain store needs you to leave with something from the case, financed if necessary. Neither of them works for you.
I do. I hold no inventory, and I buy to build: your stone, sourced from reputable dealers after you’ve told me the look and the number. Bring me the listing, a finished ring or a loose stone, or any written quote, and I’ll put my number next to it on the same specifications. If their deal is genuinely better, I’ll tell you to take it.
How most of these start: a link.
Natural or lab-grown
A natural diamond and a lab-grown diamond can both make a beautiful engagement ring. The difference is not whether one can look good. The difference is origin, rarity, budget, size, and what the stone means to the person wearing it.
Choose natural when geological origin is part of the emotion.
A natural diamond was formed by the earth over an extraordinary amount of time. For some couples, that origin is part of the meaning. They want the traditional diamond category: geological, finite, and naturally formed.
Choose lab-grown when the ring you picture matters most.
A lab-grown diamond has a different origin, but it can give you a larger or more specific center stone within the same budget. For many couples, that means the ring can look closer to the inspiration photo without forcing the budget higher.
The real question
The easiest way to choose is to compare both paths in the same ring direction. Oval vs oval. Radiant vs radiant. Solitaire vs solitaire. Same setting idea, same budget range, two different diamond origins.
I hold no inventory, so I have no stone to push you toward. I’ll walk you through what changes, what stays the same, and what each choice means before the ring is made.

“We walked in thinking $3,500 wouldn’t get us anything special. Andrew built Jasmine an oval that gets compliments almost weekly, and he never once tried to push us past our number.”
Tyler & Jasmine
Custom oval engagement ring
“I had about three weeks before I shipped out and every store quoted me six to eight. Andrew asked for my date, said that’s doable, and the ring was in my hand in 17 days. She said yes with time to spare.”
Sean
Engagement ring on a deployment timeline
“He put two diamonds with nearly identical reports under the loupe and showed me exactly why the cheaper one wasn’t the better deal. I have never had anyone in a sales situation talk me out of spending money before.”
Priya
Radiant engagement ring
“We came in with a screenshot from one of the big diamond websites, basically daring him. He sourced the same specs with a noticeably better stone, side by side you could see it, and his number was lower. Honestly didn’t expect that.”
Miguel & Sofia
Compared against an online listing
Straight talk about money
The number you are comfortable with is the number I design to. Tell me what it is and you will get a straight answer about what it buys, where I would put it, and where I would not bother. Nothing you pay here is covering a showroom, which is the whole reason the same money goes further.
The money side stays simple: a short written contract, a deposit so I can source your stone, and the balance settled before your ring is finished. Custom work is made to order, so nothing goes into final production on credit. Most rings are done in 14–30 days.
See what your budget buysYou set it, I design to it. A stone chosen in person, a setting that fits her hand, and nothing decided for you in advance.
For the ring that shouldn't exist twice: rarer stones, fully built settings, pieces designed around a specific person.
Everything in writing before anything starts, and the balance settled before the ring is completed. No store cards, no financing desk theater.

Explore this pathBuilt for you, which is not the same as built from scratch. Sometimes I source the exact diamond and set it in a setting that already exists. Sometimes I modify a strong foundation. CAD comes in only when the right ring needs to be created around your stone. Custom doesn’t mean more expensive; it means nothing is decided for you in advance.
Yes, and it’s the best first step. A screenshot shows me proportion, mood, shape, and details, and I can usually tell you the smartest path from one image. Text it to (619) 279-7738.
Both, and I don’t care which you choose. I hold no inventory, so I have no stone to push. I’ll put a natural and a lab-grown next to each other in the same shape and budget and let your own eyes decide.
Most rings finish in 14–30 days. CAD work or unusual stones can run longer, and you’ll know the realistic window before any deposit changes hands.
It depends on the stone more than anything else, and I design to your number rather than quoting one at you. Tell me the range you're comfortable with and you'll get a plain answer about what it buys in the shape you want, in writing, before anything is ordered. The mechanics never change: a short written contract, a deposit so I can source your stone, and the balance settled before it is finished.
Yes. Bring the stone and its report and I'll tell you honestly what you have before we design around it. But if you haven't bought it yet, send me the listing first: a stone bought off a report alone, from an auction, a bulk broker, or a social-media shop, skips every check a private jeweler makes by eye.
We start on the phone. A consultation call covers what you're after, the budget, and the plan, and most of the work runs from there by phone and text. When I've sourced stones for your ring, we meet in person at the Jewelers Exchange so you can see them next to their reports before anything is made.

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.
