G7 traceability mechanism implementation delayed for a second time
Plans to support diamond sanctions on Russia with a blockchain-backed traceability mechanism have been delayed for a second time.The G7 and EU nations originally intended to implement the scheme on 1 September 2024, but in June 2024 it was put back to March 2025. And last week it was delayed again, until 1 January 2026.
The announcement was made last week in the 16th sanctions package against Russia, marking the third anniversary of its invasion of Ukraine.The postponement has been widely welcomed within the industry, where many feel the introduction would otherwise be rushed and poorly planned.

The Antwerp World Diamond Centre (AWDC) said an additional 10 months would give diamond companies time to prepare properly. The new sanctions package also requires diamond traders importing rough diamonds of mixed origin to present a Kimberley Process certificate listing all countries of origin “At this stage, there is still considerable uncertainty about how the traceability system will function and how it will be governed, and the G7 must first clarify these aspects,” said CEO Karen Rentmeesters

Global Diamond Markets and Overall Prices Remain Steady
Steady Prices Mask A Polarizing Market Where Specific Large Shapes Win and Poorly Cut Diamonds Stagnate.
The natural diamond and high-end jewelry sectors are experiencing a period of selective resilience. While macro-market prices remain steady, structural shifts in consumer preference, inventory drawdowns, and geographic demand variations are creating distinct “winners and losers” across diamond cuts, sizes, and geographies.
- Macro Overview: Global markets and overall prices remain steady. Dossier prices continue to recover—particularly in the 0.30 ct. round collection goods—following a significant inventory drop.
- B2B Buyer Behavior: Demand remains patchy. Wholesale buyers are strictly purchasing to fulfill specific, pre-existing orders rather than buying for inventory.
- Category Winners: Sales are heavily concentrated in 2-carat and larger diamonds. While rounds are stable, long fancy shapes (Ovals, Marquises, Emeralds) are outperforming rounds in the 2 ct.+ category. High-quality Marquises, long Radiants, and long Cushions are in short supply.
- Shape Premiums & Trends: > * Marquise is currently the most expensive fancy shape.
- Long Cushions are highly liquid, trading at a 20% to 25% premium over square cushions.
- Antique cuts/styles and well-proportioned, elongated Ovals (D–I color, VS–SI clarity) see robust demand, especially in the US.
- Illiquidity Risk: Poorly proportioned fancy shapes remain entirely illiquid.
