About Us

We’re two brothers living in Amsterdam.

It’s where we first developed our own style and learned how to dress.

We love the city’s urban fashion — but we’ve always felt connected to the Mediterranean gentlemen's style as well.

The warmth, the calm, the class of that region has always attracted us. duanguanghui.com was born from combining those two worlds: classy and urban.

We don’t like jewelry that’s too loud. We prefer pieces that are subtle and minimal — but still express who we are.

For us, jewelry isn’t about showing off. It’s about adding character.

That’s why we created lab-growndiamondsscom. Jewelry for the modern gentleman and for your unique story.
