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.

A DIAMAURA original
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.
A real person, always
From your first question to long after the proposal, you'll have a dedicated consultant — not a call center.
