When you fall in love with a diamond — that perfect shimmer, that way it catches light from every angle — it’s natural to wonder: is it real?
With the rise of lab-grown diamonds, more and more people are asking one big question:
Do lab-grown diamonds pass a diamond tester?
Let’s dive into it — and see why lab-grown diamonds might just be the smartest sparkle you can choose.
So, Do Lab-Grown Diamonds Actually Pass the Test?
The short answer: Yes, they do.
Lab-grown diamonds are real diamonds — not imitations, not simulants, not “fake” in any way. They’re made from the same carbon crystal structure as natural diamonds and share identical chemical, physical, and optical properties.
So when a diamond tester measures heat or electrical conductivity (the main ways testers detect a diamond’s authenticity), a lab-grown diamond will register exactly the same as one formed in the earth.
That means —
✅ It sparkles the same way.
✅ It’s just as durable.
✅ It passes the diamond tester.
At OBY, we believe that beauty should never come at the expense of ethics. That’s why all our diamond pieces are made using lab-grown stones — every bit as real, every bit as radiant, and far more responsible.
How to Tell the Difference
Visually? You can’t tell them apart. Even professional gemologists need special lab equipment to distinguish a lab-grown diamond from a mined one.
And here’s the thing:
Why should you care where it was formed, when what truly matters is how it makes you feel when you wear it?
A lab-grown diamond carries the same fire and brilliance — but it also carries a story of innovation, ethics, and conscious beauty. It’s the diamond of the future, made for people who care about more than just shine.
Why We Choose Lab-Grown at OBY
We’ve always believed jewelry should represent more than just decoration — it’s a reflection of your values, your confidence, your light.
That’s why every OBY diamond piece is crafted from lab-grown diamonds set in recycled sterling silver or gold vermeil, combining timeless elegance with modern sustainability.
From our Diamond Flow Loop Bangle to our Celestial Heart Necklace, each piece tells a story of mindful luxury — one that you can wear every single day, guilt-free and glowing.
Because true beauty isn’t just seen — it’s felt.
So, yes — lab-grown diamonds do pass a diamond tester.
But more importantly, they pass a deeper kind of test — the test of time, ethics, and authenticity.
They’re proof that luxury can be kind, and that brilliance can come with purpose.
When you wear a lab-grown diamond, you’re not compromising. You’re choosing better — for yourself, and for the world.
