What will the impact be of De Beers rough auction sales announcement?


A recent announcement to the diamond trade by Neil Ventura, Executive Vice-President, Auction Sales, at De Beers showed the direction that the mining giant heading in regarding auction sales. He said that the De Beers Auction Sales business has "acted as a catalyst for widespread industry change in selling practices" and now "the vast majority of producers of all sizes, including even producer country governments, have adopted auctions for at least a part of their overall sales mix. The firm has developed its auction program to enable customers to secure future supply at its auctions by launching a forward contract sales program to enable customers to do so. It then further developed the system from a floating price system to fixed prices. Last year, the miner started selling its own polished diamonds, as well as allowing third parties to sell their polished goods on the De Beers platform. The miner said that its aim was to provide customers with a ‘one-stop shop’ for its sourcing needs – saying this offers benefits in terms of efficiencies and reduced costs. Although diamond manufacturers – especially De Beers' sightholders – won't publicly comment, off the record they are not exactly delighted by the move.

Responsible supply chains sine qua non for diamonds, other precious stones

09 april 2018

The Kimberley Process Certification Scheme (KP), which was established by the southern African diamond-producing countries in 2000, came into effect on 1 January 2003 in a bid to eliminate the use of rough diamonds to finance armed conflict. The scheme, currently under the leadership of the European Union (EU), also aimed at protecting the legitimate diamond industry, upon which many countries depended.  KP, which was also endorsed by the United Nations’ General Assembly, made a massive contribution during its formative stage to the implementation of then fragile peace agreements in Angola, the Democratic Republic of the Congo, Liberia and Sierra Leone by blocking resources to potential spoilers.  The scheme members are now said to be responsible for stemming 99.8 percent of the global production of conflict diamonds. However, some non-governmental organisations (NGOs) are not convinced that KP had made such an astounding progress.

Diamond producers can’t rest on their laurels in the face of synthetics threat

12 march 2018

In January 2017 I asked the then De Beers head of media relations Lynette Gould whether natural diamond producers were worried that they might lose some market share to lab-grown stones. She was dismissive in her response, claiming that natural diamonds and synthetics were two different propositions. “Our research consistently shows that consumers do not see synthetic diamonds as potential substitutes for natural diamonds,” said the De Beers spokesperson at the time. She, however, said that the challenge that they needed to focus on was ensuring the reputation of the industry – and the integrity of the product we sell – was beyond question. “Challenges to product integrity, such as the risk of undisclosed synthetics infiltrating the pipeline, are things that we take very seriously,” said Gould.

So, it is helpful to use the historical cases demonstrating the triumph of common sense and desire for constructive development over tactical political interests.
