Hi, Sarah,
Make sure you are using the guide: http://libguides.unomaha.edu/business_economics. Under the tab INDUSTRY Information, use IBISWorld to find industry information on "diamond industry." Several will display from the United States on retail, manufacturing, mining and distribution. You might have to use all for each part of the chain.
Also on the first page of the guide, use Business Source Complete, type in diamond industry AND industry profile. You shoudl receive back several industry profiles from different countries.
Also in BSC type in "diamond industry" and Sierra Leone OR "diamond industry" and Botswana or any country you are interested in pursuing.
Another database with marketing information is Passport by Euromonitor on the same page as IBISWorld. On Passport, top right, type in diamonds and a long list of information from different countries will display.
Please email me with any further questions, Nora (nhillyer@unomaha.edu).
