The Tanzania Gemological Centre was formed in the year 2003, with an objective to offer inhouse training on Gem and Rock Carving so as to enhance value addition skills. The centre was known as Arusha Gemstone Carving Centre (AGCC) until year 2009 when the name was changed to Tanzania Gemmological Centre (TGC). The changes were due to the changes in the National Minerals Policy which lead to the changes in the objectives of the centre to include Gemmology, Lapidary and Jewellery training. Tanzania Gemmological Centre is registed under NACTE with a registration number REG/SAT/033.
