De Beers leaves rough prices unchanged at the first cycle of the year

De Beers left rough prices unchanged at the first cycle of the year after December’s sharp reductions. It allowed 20% buybacks for all goods — a mechanism that lets sightholders sell the least profitable stones back to the company. Demand was weak, with sales value expected to be low.

But the question on sightholders’ lips was what would happen next. One of the main reasons for the low sales was De Beers’ high prices. The miner’s rough remains significantly more expensive than the tender and auction market.

The company’s December price change of 10% to 15% went only part of the way toward closing this gap. Russian rival Alrosa has now reached similar price levels: It followed a December cut of around 10% with a further one of 7% to 8% in January, market insiders said.

The World Diamond Council (WDC) has fully transitioned to an expanded System of Warranties, broadening its scope beyond conflict diamonds to encompass human rights, labor standards, anti-corruption, and anti-money laundering controls across the global diamond supply chain.

First introduced in 2002 to complement the Kimberley Process for rough diamonds, the voluntary self-regulatory system applies to transactions involving polished diamonds and finished jewelry.

Following a five-year transition period that concluded on Sept. 21, companies trading in diamonds are now required to register on a dedicated WDC digital platform and complete an annual online self-assessment to maintain compliance.

Upon completing the evaluation, businesses receive a unique identification number to include alongside updated warranty declarations on commercial invoices and memos. The WDC initiated the revision in 2017 to modernize industry self-regulation and ensure broader ethical sourcing standards across intermediate and retail markets.
