One Family · Every Step
We Don't Resell Rings. We Make Them — From Sketch To Your Hand.
From the moment your ring enters production, we film it — and share it with you as it happens. Your Crafting Film arrives in three chapters.
Design
An in-house studio that spent 30 years crafting for the world's great jewelry houses.
Craft
Set and polished by hand in our own atelier — every stage signed.
Film
Optionally, the making of your ring captured on camera — a service only DiamAura can offer.
Deliver
Straight from our hands to yours. No middlemen, no markups.
A Young Brand · A Deep Heritage
New To You In 2022. Three Decades In The Making.
30+
Years crafting fine jewelry as a family — the manufacturer behind pieces for the world's leading international brands.
2022
DiamAura launches online — our family's craft, finally under our own name.
2025
Our first showroom opens in San Jose, California.
“My family spent thirty years making jewelry for famous names. I spent mine as an engineer at Microsoft and Google. DiamAura is what happens when those two worlds meet.”
The DiamAura Standard
Three Things No One Else In North America Offers.
Top-Grade Accent Diamonds
Every accent stone we set is D–F color, VS clarity or better. Thirty years of supply chain lets us afford what others can't.
Your Ring, Filmed
The only jeweler in North America that can film your ring's entire creation — available as an optional add-on, because the factory and design team are truly ours.
Sketch To Launch
A new design goes from our studio to the site in 21 days — tested first with our hundreds of thousands of social followers.
The Design Studio
Always The Newest Designs. Because We Make Our Own.
Brands that resell finished rings can't update their catalog. We refresh ours every quarter - and take on work most jewelers won't touch.
Day 1
Every new style begins as a hand-made sample in our atelier.
The sketch
Our designers draft a new style - informed by what couples are actually asking for.
Day 7
Accent stones, set by hand.
First sample, made & posted
We craft the first piece by hand, film it, and post it to our social channels - hundreds of thousands of followers tell us what they love.
Day 21
Polish, inspect, sign.
Live on the site
The styles our community loves go into production and onto the site - a new collection every quarter.
Bespoke Commissions
Have Something Only You Can Picture?
From engagement rings to diamond tiaras and evening necklaces - if you can describe it, our atelier can make it.
Tell us your idea
A photo, a sketch, or just words - in person or online.
See it in 3D
We send a photorealistic 3D render of your piece - revised until it's exactly right.
Approve, then we craft
Nothing goes into production until you've signed off on every detail.
The DiamAura Experience
First, A Lesson. Then, A Ring.
Every appointment - in our San Jose showroom or online - begins with a short class in diamonds, so you choose from understanding, never pressure.
Reserve your hour
A private room in San Jose, or meet us online. Walk-ins welcome too.
Learn the essentials
Cut, color, clarity, carat - and what actually matters for your budget.
Choose stone & design
Certified diamonds, in-house designs, or something custom - with a 3D render.
We craft & film
Made by hand in our atelier, every stage signed by its craftsman.
The handover
Your ring, its certificate - and your Crafting Film, if you chose one.
Who You'll Meet
Consultants Trained As Designers — Not Salespeople.

A Signature Service · Optional Add-On
Your Ring Crafting Film.
An optional service, exclusive to DiamAura: we film the making of your ring — from the moment your diamond is chosen to its final polish.
The hands that made it
Your master setter, designer, client specialist, and quality inspector each sign and seal the certificate by hand.
Made for two
The one who chose it, and the one it was made for — your two signatures complete the record.
Scan to watch, forever
A QR code on the certificate plays your Crafting Film back anytime — for the rest of your lives.
An honest note: the Crafting Film is a paid add-on service. It's a real, days-long production — and the modest fee we charge covers only a fraction of what it costs us to make. We offer it anyway, because how your forever began deserves to be remembered.
What We Believe
We never set out to be the cheapest ring online. We set out to match the world's finest quality — at the lowest price that quality allows.
How Most Brands Work
The DiamAura way
Looks beautiful on the website — feels thin and light in your hand
Every ring is built with the materials and craftsmanship it deserves—not the minimum needed to lower the cost.
Rings bought finished from third-party suppliers
Designed and crafted entirely in our own atelier
No design team, so the catalog never changes
New designs every quarter, live in 21 days
Price cut by cutting the gold, the stones, the craft
Honest price — because there's no one in the middle
VS
Backed By Six Promises
Every Reason To Feel Completely At Ease.
Independently certified
IGI/GIA grading report — plus our Dual-Signature Certificate, signed by the makers and by you.
Lifetime care
Free cleaning, inspection, and prong checks for life — plus complimentary resizing.
Transparent pricing
No chain of middlemen. The price you see is honest — no markups, no games.
Fully insured delivery
Insured, signature-required, tracked from our hands to yours — with an appraisal included.
Easy returns
30 days to change your mind. Certainty shouldn't end at checkout.
A real person, always
A dedicated consultant from first question to long after the proposal — never a call center.

About Us · Est. 2022 · San Jose, California
The Engagement Ring, Without The Anxiety.
DiamAura was founded on a single conviction — that choosing the ring for the most important question of your life should feel clear, calm, and entirely your own.
Read Our StoryWHY WE EXIST
Buying A Diamond
Shouldn't Feel Like A Test
You Never Studied For.
Most people walk into a jewelry store about to spend a great deal of money on something they were never taught to understand.
The pressure is real. The jargon is intimidating. And the usual sales tactics only make the panic worse.
We built DiamAura to be the opposite of that. Every appointment begins not with a pitch, but with a lesson — so that by the time you choose, you're choosing from a place of understanding, not fear.
We want you to leave certain. Certain about the diamond, certain about the design, and certain that you were never sold anything you didn't fully understand.
A note from our founder
I grew up in a family that has grown and set diamonds for more than thirty years. I spent my own career as a software engineer — at Microsoft, then Google — and the more I learned about how engagement rings are actually sold, the more I knew something had to change.
So I brought two worlds together: my family's craft, and an engineer's obsession with precision, transparency, and a better experience. No pressure, no jargon, no tricks — just an honest process, a ring made by people who sign their work, and the certainty that you got it right.
Come sit with us. Let us teach you. Then decide.

A young brand · a deep heritage
New To You In 2022.
Three Decades In The
Making.
DiamAura is a young name — we opened our doors to couples in 2022. But we never started from zero.
The brand was born from a family with more than thirty years of experience growing and crafting diamonds — from the science of creating the stone itself to the art of setting it by hand. The brand is new; the mastery behind it is not.
That heritage is why we don't resell anyone else's rings. We grow our own diamonds, design every piece in-house, and set them in our own atelier.
Traditional mall jewelers place one large order a year and then wait — slow to respond, locked into whatever they bought months ago. We move at the speed of our own studio: a new design goes from sketch to live in as little as 30 days, with a new collection every quarter.

Your Ring Crafting Film.
We are the only jeweler that films the making of your ring — from the moment your diamond is chosen to its final polish.
The makers
Signed by hand
At every stage — especially quality control — the responsible craftsman signs off on their work. You see the very hands that brought your ring to life, each one a contributor to your story.
The couple
Signed by you
When your ring is complete, you and the person you're proposing to sign it too. Everyone who touched the journey becomes part of one shared record.
The keepsake
Yours alone
Your showroom appointment, your online consultations, and even the moment you collect the ring — all filmed, edited, and woven into a keepsake that exists for no other couple on earth.
Every ring carries a small engraved QR code. Scan it, and your film plays back — the craft, the signatures, and the moment it all began.
Your Ring Crafting Film is a considered add-on rather than a complimentary service — because it is a genuine production. For the couples who choose it, it becomes the most meaningful record of how their forever began.
Why lab-grown
A Real Diamond. A Clearer
Conscience. A Better
Value.
A lab-grown diamond is, in every way that counts, a real diamond — chemically, physically, and optically identical to one pulled from the earth. The only difference is where it began.
Every DiamAura stone is independently certified, so you never have to take our word for its quality.
Origin you can feel good about. No mines, no ambiguity — a diamond grown with care, not extracted at a cost.
More diamond for your budget. Because we grow and craft our own, you get a larger, finer stone for the same investment — and an honest price with no middleman markup.
Our promise to you
Every Reason To Feel
Completely At Ease.
Independently certified
Every diamond arrives with an independent grading report — plus our own Dual-Signature Certificate, signed by the makers and by you.
Lifetime care
Free cleaning, inspection, and prong checks for life — and complimentary resizing so the fit is always perfect.
Transparent pricing
Because we grow and craft our own diamonds, there's no chain of middlemen. The price you see is honest — no markups, no games.
Fully insured delivery
Every ring ships fully insured and signature-required — tracked from our hands to yours, and arriving with an appraisal for your own coverage.
Easy returns
If something isn't right, our return policy makes it simple to put it right. Certainty shouldn't end at checkout.
