Diamond-mine owners like De Beers have been unable to prevent prices from dropping below where they were a decade ago, a sign the industry is failing to maintain the cachet of its brand.
In the diamond industry, even the crooks are old-fashioned.
The ringleaders jailed for a $20 million jewelry heist in London last year were in their 60s or 70s, so it’s no surprise they’d go after the gems.
They’re old enough to remember when advertisers said diamonds were forever and Marilyn Monroe sang they were a girl’s best friend.
Not anymore. Diamonds are losing their allure for many consumers more interested in spending money on vacations, fancy handbags and high-tech gadgets. Mine owners like De Beers — who helped dream up those successful marketing campaigns in years past — have been unable to prevent prices from dropping below where they were a decade ago, a sign the industry is failing to maintain the cachet of its brand.

“I’m not really a jewelry person,” said Catherine Weir, 32, who was window shopping last month with her fiancé in Hatton Garden, London’s jewelry district, just yards from the site of the Easter-weekend heist. “It was always diamonds for an engagement ring, maybe for a wedding band and that’s it. IPads and things like that are much more accessible.”
Diamonds are now cheaper than they were in 2006, data from PolishedPrices.com show. Over the same period, the price of luxury items like cars, shoes and fine foods have risen at above-inflation rates, according to a Forbes index.
Demand for luxury jewelry rose just 1.9 percent a year from 2004 to 2013, trailing high-end beauty products, tobacco and watches, according to De Beers’s 2014 Insight Report on industry trends.
Efforts by producers to push prices higher in the past five years unraveled in 2015. Polishers who buy the raw gems and sell to wholesalers and retailers were unable to pass on the higher costs as consumers balked.
A threat to boycott auctions of rough gems by buyers in India, where almost 90 percent of the stones are cut, ended with De Beers lowering prices 15 percent for the year and 7 percent more in January.
“Producers cannot simply just increase rough prices and expect consumers to pay more for diamond jewelry,” said Anish Aggarwal, a partner at industry consultant Gemdax in Antwerp.
“Consumer demand cannot be taken for granted, even in mature markets and especially with millennials,” Aggarwal said.
Earlier generations were easier to influence.
De Beers’ monopoly on diamonds in the 20th century meant money spent on persuading consumers to pay high-end prices for commodity minerals paid off in surging sales. The investment led in the 1940s to creation of the slogan “A diamond is forever,” and the industry heavily promoted the gems for engagement rings.
Jewelers loaned pieces to celebrities like Monroe and 1944 best actress Oscar winner Jennifer Jones to create a buzz around the product as a luxury item.
The new millennium brought the end of the monopoly, meaning other suppliers were able to sell their gems piggybacking on De Beers’ advertising. The company cut its annual marketing budget in half to about $100 million.
“The industry is a victim of its own history,” said Charles Wyndham, a former sales director at De Beers and founder of WWW International Diamond Consultants. “Everyone had a pretty easy ride when De Beers had its monopoly. Everybody has got to think how they can turn it around. It requires a huge cultural change.”
De Beers is getting the message. On top of its global advertising spending, the company plowed tens of millions of dollars into a push to spur jewelry sales in the key U.S. and Chinese markets in 2015.
Last year’s creation of the Diamond Producers Association, bringing De Beers and Alrosa together with Rio Tinto Group, Dominion Diamond, Lucara Diamond, Petra Diamonds and Gem Diamonds, seeks to revive the kind of industrywide advertising seen during the monopoly years.
In one early positive omen, De Beers managed to raise rough prices by as much as 2 percent in a sale last week, the first increase in more than a year.
“It’s got to come down to ad-spend,” said Ben Davis, a mining analyst at Liberum Capital. “They just need to bite the bullet.”
