The major world diamond market companies are closed family businesses. The level of their transparency as compared to that of public companies is traditionally low, there being hardly any prospects for the situation to change in the nearest future. In the given state of affairs the mass media messages on such enterprises and their owners have greater influence which, in its turn, results in aggravating the reputation risks of the branch on the whole since mass media are frequently employed as instruments of business and political competition which is often far from being bona fide.

Under the above circumstances generation and regular factual verification of press-portraits of the major diamond market participants combined with expert analysis of the data sources reliability is an urgent necessity. It seems to be next to the only instrument available for bringing the transparency of the market in question to the currently required standard.
