HB Antwerp reveals historic collection of rare, recently discovered diamonds

In a momentous event highlighting the unparalleled rarity of natural diamonds, HB Antwerp today unveiled a collection of recently discovered, headline-making stones. The showcase features some of the most significant and most exceptional diamonds recovered in recent history, each a testament to a “miracle of Mother Nature” and a powerful display of the company’s groundbreaking approach to the diamond industry.

The collection includes four world-renowned stones found in the Karowe Mine in Botswana:

• The 2,488-carat Motswedi: The second-largest diamond ever found, discovered in August 2024.
• The 2,035-carat diamond: The third-largest diamond ever found, discovered in July 2025.
• The 1,094-carat Seriti: Found exactly one year ago, this stone is celebrated for its rare combination of outstanding size and quality.
• The 37.42-carat pink diamond: Discovered just a few weeks ago, this diamond is notable for its exceptional color.

HB Antwerp’s Unique Approach to Transparency and Heritage

Finding a single one-carat diamond requires miners to move and process an average of 250 tons of rock and soil. Despite over 165 years of mining, all gem-quality diamonds ever found could still fit inside a single double-decker bus. This extreme rarity is at the core of HB Antwerp’s mission.

“What you are looking at is history in the making,” HB Antwerp-CEO Oded Mansori stated. “Our secret is in our name: it’s because we are HB, and it’s because we are based in Antwerp.”

Founded five years ago, HB Antwerp has quickly established itself as a leader in the diamond industry. The company distinguishes itself through an innovative, transparent ecosystem that combines Antwerp’s rich diamond heritage with cutting-edge, in-house developed technology. Through its partnership with Lucara Diamond Corp., HB Antwerp secures all exceptional diamonds over 10.8 carats from Botswana’s renowned Karowe Mine.

“Every stone is meticulously analyzed, cut, and polished to perfection—ensuring precision at every step,” explains Oded Mansori. “At the forefront of this transformation is HB’s in-house innovation, the HB Hyperloupe. This advanced technology redefines the standards for analyzing, marking, and preparing rough diamonds—handling stones up to 6,000 carats with unmatched accuracy. Exclusively developed for HB’s internal use, it secures a unique competitive edge in the industry.”

Every HB diamond comes with a digital twin, a blockchain-verified ledger that records the entire transformation process from rough stone to polished gem. This ledger, accessible to the end consumer, provides a transparent and traceable origin for every stone, ensuring each diamond is crafted with state-of-the-art technology and expertise.

Creating a Positive Impact

The company’s commitment to traceability goes beyond consumer confidence. HB Antwerp’s model ensures that countries of origin, like Botswana, where these stones were mined, directly benefit from the value of their natural resources.

The natural diamond industry supports the livelihoods of 11 million people globally, providing essential services such as healthcare, education, and infrastructure. By working directly with mines, HB Antwerp ensures that countries of origin are aware of the exact destination and value of their diamonds, creating a more equitable and transparent supply chain for all parties involved.
