De Beers taps into polished diamonds market with first-time auction

DTC De Beers

Anglo American’s De Beers, the world’s largest rough diamond producer by value, has decided to begin selling its own polished diamonds in auctions for the first time in its history.

The pilot auction, scheduled for June, will include a wide range of polished stones manufactured directly from the company’s own rough diamonds.

"The pilot auction, scheduled for June 29, will include a wide range of polished stones manufactured directly from De Beer’s own rough diamonds." All the polished rocks will carry grading reports from both the International Institute of Diamond Grading & Research (IIDGR) — De Beers’ in-house grading unit — and the Gemological Institute of America (GIA).

“We are interested in testing the level of demand from polished buyers for diamonds that have a clear and attractive source of origin, and that offer the assurance of product integrity that dual certification provides,” Neil Ventura, the miner’s executive vice president of auction sales, said in the statement.

If successful, the process would provide De Beers with more insight into the polished market, while also helping consumers fill gaps in supply or inventory if they were unable to find goods at the company’s rough auctions, he added.

All registered De Beers auction buyers will be eligible to bid in the first sale, which takes place on June 29.

European Union diplomats are touring the controversial Marange diamond fields.


The diplomats will visit four companies, Mbada, Marange Resources, Diamond Mining Corporation (DMC) and Anjin. They will also visit the ZRP Diamond Base.

Diamonds from Marange have courted controversy amid calls by civil society organisations that there is no transparency in the marketing of the gems.

Finance minister Tendai Biti has been complaining that Anjin has not been remitting money to treasury. Anjin is a joint venture between the Chinese and the Zimbabwe Defence Industries.

Biti has said despite claims that the Zimbabwe Mining Development Corporation (ZMDC) owns Anjin, the state entity had no equity in the diamond producer.


No Credit, No Cry

A hot-button topic in today’s diamond industry is the practice of extending credit to customers.

In several impassioned “State of the Diamond Industry” addresses, Rapaport Group Chairman Martin Rapaport said the jewelry industry cannot extend credit to customers anymore, and made clear his feelings on buying diamonds on credit (‘credit memo’).

“I’m going to blast the hell out of credit,” Rapaport said before launching into his tirade. “It makes me want to throw up.” He said that we simply cannot sell to people on credit anymore, and that diamonds at all levels of the trade must be sold to “real” buyers who actually have the money to pay for them.

“You need real people with real money,” he said. “We can’t memo our way out of the recession.”

“If you don’t have the money and are not a player we love you, but you’re not a player.”

The diamond market relies too heavily on credit to finance the jewelry sector, and hurts it when stores file for bankruptcy as happens all too frequently in today’s economy.

“Just say no to memo and encourage cash purchases”. The jewelry industry must avoid those who are not financially capable of buying stones and paying their debts.

“You don’t have money, go screw yourself. That’s the bottom line,” Rapaport said, a statement that drew a hearty round of applause from the audience.

DCLA would like to help legitimate industry members protect their money and time by limiting bad payments and default debtors. As a central hub in the Australian market, DCLA is happy to verify and give good credit information to industry members.

Diamond dealers and jewellers are also welcome to call and receive information on companies or individuals having defaulted on a payment.

Also, please note that DCLA will be closing all customer credit accounts outstanding for a period greater than 60 days.
