De Beers Sightholders report shortages of large diamonds
Rough diamonds above 5 carats were in tight supply at this week’s sight, customers reported, with explanations ranging from production cuts to ’ strategy of withholding supply. The February trading session saw stable prices in the vast majority of categories, as the miner maintained its policy of not flooding the market, insiders said this week.
The lack of large stones has puzzled some, since De Beers is reportedly sitting on $2 billion of inventories, its largest since the 2008 financial crisis. Many market insiders viewed it as a positive that these sizes were hard to find, reflecting that the categories had sold better in the past few sights. The resultant polished — mostly 2 carats and larger — has performed better in the recent downturn than 0.30- to 2 carat goods.
Some point to a tactical effort by De Beers to limit supply — either to protect the market or to reward sightholders that purchase less sought-after items.

CIBJO Backs ‘synthetic’ As Sole Label For Man-Made Diamonds
CIBJO’s Laboratory-Grown Diamond Committee, Told Delegates That “Synthetic” Remains The Primary Term Recognized By Consumers, Despite A Formal Push From The Sector’s Steering Committee To Defer The Ruling and Authorize “Laboratory-Grown.”
The World Jewellery Confederation (CIBJO) has recommended “synthetic” as the only acceptable descriptor for non-mined diamonds, rejecting calls from trade leaders to permit the term “laboratory-grown,” the organization said on Monday.
The decision, finalized at the closing session of the 2026 CIBJO Congress, deepens a global divide over gemstone terminology at a time when manufactured stones are rapidly eroding the market share and pricing power of mined gems.
CIBJO’s Laboratory-Grown Diamond Committee, told delegates that “synthetic” remains the primary term recognized by consumers, despite a formal push from the sector’s steering committee to defer the ruling and authorize “laboratory-grown.”
CIBJO’s move aligns with a growing regulatory push in several major markets. France restricted terminology to “synthetic” in 2024, Russia followed suit in June, and the London Diamond Bourse endorsed the single descriptor on Sunday. In May, the African Diamond Producers Association also tightened descriptor rules to shield the natural diamond trade.
In contrast, regulators and retailers in the United States and India have favored consumer-friendly phrases such as “lab-grown” or “laboratory-grown.” The commercial stakes are particularly high in the U.S., where synthetic stones now account for more than half of all engagement ring sales by volume, applying severe downward price pressure on natural rough and polished stones.
CIBJO, which began moving to strike “lab-grown” from its influential Diamond Blue Book standards last year, warned that the diverging legal frameworks are leaving the global market increasingly fragmented.
