Open the lid of a jewelry box, and you’ll see a ring that catches the light — perhaps a halo engagement ring, its sparkle powered by Grunberger’s Ideal Cut melee diamonds. But those diamonds didn’t start here. Their journey began long before, shaped by careful sourcing, expert cutting, and a commitment to quality. Here’s how they made their way from the earth to your jewelry box.
Sourcing with Integrity
The journey begins long before cutting or polishing. At Grunberger Diamonds, we believe that transparency starts at the source. That’s why all of our melee diamonds are ethically and responsibly sourced. We work only with trusted partners who follow the highest international standards, so that every diamond we receive has a clean, conflict-free origin.
As a trusted melee diamond supplier, our commitment to ethical practices is not just a part of our process. It’s a cornerstone of who we are.
Evaluating and Sorting the Rough
Once the rough diamonds arrive at our Antwerp office, each parcel undergoes a detailed evaluation. Our skilled team meticulously sorts stones based on quality, color, and potential yield. This early stage sets the tone for the high standards we uphold throughout the process.
Precision Cutting for Maximum Brilliance
The rough melee diamond is then transported to our family-owned cutting facility in Vietnam. Every single stone is cut with extreme care to meet our Ideal Cut standards, delivering the highest levels of fire, brilliance, and scintillation. Whether we’re cutting a 0.70mm diamond or a 3.00mm stone, precision is non-negotiable. Our Ideal Cut melee diamonds showcase the coveted Hearts and Arrows pattern, a sign of optical symmetry and superior craftsmanship.
Quality Checks That Go Beyond the Surface
Each melee diamond is measured within 0.025mm tolerance and undergoes multiple rounds of quality control, because even the smallest inconsistencies can impact a finished piece. Using advanced diamond testing equipment, we ensure every diamond meets the strictest visual and structural benchmarks.
Matching Melee for the Perfect Design
Back at our distribution center, stones are sorted again to ensure perfect matches by size, color, and clarity. Whether a jeweler needs a layout for a vintage-inspired setting or a modern halo design, our diamonds arrive ready to be set without additional sorting.

A Sparkling Legacy, Passed Down
Now, back to the jewelry box. That halo ring didn’t just come together overnight. Every one of its melee diamonds passed through careful hands, precise tools, and rigorous testing. The result? A ring that not only dazzles today but is built to last for generations.
As a leading melee diamond supplier, Grunberger Diamonds stands behind every stone we deliver. Because for us, brilliance isn’t about the journey.
