Five Star Diamond's business is diamond development. It is focused on acquiring and developing advanced staged diamond projects in Brazil. Since it was established, it has pursued an accelerated growth strategy and aims to be one of the first producers of diamonds from kimberlite deposits in Brazil. The Company is focused on the development of sustainable kimberlite pipes and is not involved in alluvial diamond mining with its associated environmental issues. The Company works closely with local, state and federal authorities in Brazil to foster an open, transparent and legal diamond industry in Brazil.

The flagship project of Five Star Diamonds is the 100% owned advanced stage Catalao diamond project located in the famous Coromandel diamond district of Brazil. The Project comprises one exploration licence covering 1,999.42 hectares. In addition, the Company has submitted applications for three exploration licences over proximate areas covering a total of 5,998.37 hectares.

In 1853, a diamond discovered in Coromandel became the first large Brazilian diamond whose history is fully authenticated. It was named "Estrela do Sul" (Star of the South) and weighed 261.9 carats. Additional notable stones discovered in the same area include one weighing 122.5 carats (found four years later, in 1857). Other notable stones authenticated are 118 carats (1929), 108 carats (1940), and 174.5 carats (1954).

A pilot plant was constructed by the Company in Catalao and commissioned, and an initial mining and pilot processing program was completed on the oxide zones at three diamond bearing kimberlite pipes. A feasibility study is currently underway to evaluate the fresh rock zone.
