Measure & Sizing

Made For You

✦ Your Perfect Fit Handcrafted for you.

Every piece is handmade and tailored for you. We believe jewelry is a reflection of who you are. It should feel as individual as you are, elevating your style with something that fits perfectly. No guessing sizes, no loose beads.


✦ How We Make It

Standard sizes can't account for every wrist, so we don't rely on them. We craft every piece to your exact wrist measurement, accounting for natural bead size variations and design specifications. After production, every piece is sized to your wrist one final time before it ships, so what arrives is truly made for you.


✦ Your Preference is Considered

Everyone wears their jewelry differently, some like it snug, others prefer room to breathe. That's why we offer three fit preferences: Tight, Standard, and Loose, so your piece feels exactly the way you want it to. Check the details in the measuring & sizing guide when you fill in your wrist size.


✦ Clasp Bracelets

A perfect fit can make fastening tricky. That's why every first-time clasp bracelet order comes with a complimentary bracelet helper, so putting it on is always effortless.

OUR STORY

✦ The Story Behind. Gemstone and Us.

Hi, we're Scott, Max — the founders of Aurum Brothers.

It started with a shared passion. Gemstones form underground over millions of years, entirely without human interference. No two come out the same. No two ever will. We found that remarkable, a true marvel of the natural world.

We couldn't understand why so few products on the market gave the stone the credit it deserved. Most brands treat it as decoration. We saw it differently. The stone isn't detail, it's the whole point.

So in 2015, even knowing nothing about business, we decided to figure it out anyway.

We spent days and nights working on our designs, our craft, our quality, the details, our customer experience. All in service of one goal: to let the stone speak for itself.

Eleven years later, there are fifteen of us in a workshop in Brabant, in the south of the Netherlands. Every piece on the site is made here, by hand, after you order it. Nothing sits on a shelf. The stone you receive is the only one of its kind, shaped by nature over millions of years, long before we ever touched it.

The Unconquerable

Long before diamonds became symbols of love, they stood for strength. The Ancient Greeks called diamond adamas, meaning "the unconquerable."

The Stone

Around three billion years old, these rough black diamonds are left uncut, exactly as the earth formed them. Most diamonds are polished to shine from every angle. We leave ours raw so the natural character stays intact. The 5 to 5.5mm stones are finished with 925 sterling silver square-disc accents and a Rumi abacus clasp.

The History

Diamonds were first mined in ancient India, where they were called vajra, meaning "thunderbolt." People believed they formed where lightning struck the earth. For thousands of years, uncut diamonds were worn as armor and protection: Indian kings wore them into battle, Roman soldiers carried them against fear, and medieval knights kept them close to the heart.

The Belief

In modern stone traditions, black diamond stands for grounding, mental clarity, and protection. Whether you take that literally or simply appreciate the symbolism, its meaning has never changed: strength under pressure.

Made to order. Hand-selected. Sized to your exact wrist.

Made with natural diamonds. Slight variations in color, size and pattern make every piece one of a kind.
