“Let us learn from this, while it is important to develop new new customers, it is important to maintain relationships with old customers. There is more to business than the latest fast buck. Loyalty and maintaining relationships serve our long term interests,” Martin Rapaport wrote in his new year message to the market.Even with the US providing support for the market, last year financial issues were unavoidably in focus. That was perhaps underscored when ABN AMRO (AMS:BGHEF), a major diamond market financier, reportedly terminated a credit facility to Arjav Diamonds and had authorities seal its safes in Antwerp due a $154-million debt. Arjav is counter suing for $230 million in damages. Major producers ALROSA and De Beers started off tightening the noose around the industry's neck with high rough diamond prices in a weak market. As a result, in addition to battling problems with liquidity and access to credit, many diamond players were also faced with meager, and sometimes non-existent margins. Eventually, sightholders got wise up and began rejecting boxes at the sights. ALROSA (MCX:ALNU) and De Beers later reduced their prices. Overall it was a year characterized by weakness and caution; many in the trade resisted building inventories and consumers displayed an overwhelming preference for lower-priced goods. 2012 saw diamond prices drop for the first time in four years, according to Bloomberg. Data from WWW International Diamond Consultants reveals that rough diamond prices plummeted 16 percent. Polished prices were also in the red for the year. The RapNet Diamond Index shows 1-carat diamond prices fell over 12.5 percent and 3-carat diamonds fell more than 11 percent. The melee index was up 2.3 percent for the year. Diamond market participants, such as De Beers, continue to portray a positive outlook for the diamond industry in the long term. Demand is expected to grow significantly as the middle classes of emerging nations, such as India and China, grow, but supply fails to keep pace. However, while there is a degree of renewed optimism about 2013, the year has started with many of the same characteristics seen in the past year, including a weak market and significant caution among industry players and consumers.
