Gems and Jewellery News: Unprecedented Auction to Offer 7.3 Million Carats of Rough Emeralds
A record-breaking auction is about to send shockwaves through the global gemstone industry. Auctim, a Belgium-based online auction house, has announced plans to release over 7.3 million carats of rough emeralds—sourced directly from a Brazilian mine—onto the international market this September. These emeralds, weighing nearly 1,500 kilograms in total and divided into 109 individual lots, represent one of the largest public offerings of rough emeralds in recent memory.

According to Auctim CEO Christophe Moyersoen, the upcoming auction stands out not only for its sheer volume but also for the diverse quality of the emeralds on offer. Approximately 10 percent of the lots are believed to contain near-gem to gem-quality stones with outstanding cutting potential and vibrant color—features that are expected to attract serious attention from global buyers. This Gems and Jewellery News report highlights that the emeralds are being sold as part of a court-mandated liquidation, adding another layer of urgency and unpredictability to the auction.
Real Time Online Auction to Let Market Decide Final Value
The online auction, set to take place from September 1 to 11, will feature real-time competitive bidding, allowing participants to view current bid amounts as they unfold—unlike traditional silent or sealed tenders. While Auctim has assigned preliminary starting prices per lot based on internal evaluations, the auction house has refrained from estimating a total market value for the entire offering.
“Given the exceptional volume and diversity of the lots, it is nearly impossible to assign a single meaningful estimate,” the company stated. “Ultimately, the true value will be defined by the market itself—through open and competitive bidding.”
Global Industry Eyes Set on September Event
Industry experts believe this auction could significantly influence short-term emerald pricing and availability across global markets. Traders, wholesalers, and jewelry manufacturers are preparing for a highly competitive bidding atmosphere. The influx of such a vast quantity of rough emeralds could temporarily ease supply constraints, particularly for mid-range commercial quality stones, while premium-grade material may spark fierce battles among high-end buyers.
With both opportunity and uncertainty looming, all eyes are now focused on Belgium this September. For buyers and collectors alike, this event may mark a rare chance to acquire Brazilian rough emeralds on an unprecedented scale.
