Pierrot, J. Toussaint, and T. Verbeek in 1965 in honor of Jean Claude Guillemin (1923–1994), a chemist and mineralogist. It is a rare uranium/selenium mineral found at the Musonoi Mine in the Katanga Province of the Democratic Republic of the Congo.[3] This secondary mineral also includes barium in its structure, in addition to selenium and uranium. It is bright yellow in colour and usually has an acicular crystal habit. It has a Mohs hardness of 2–3.[4] References1. ^[https://www.mineralienatlas.de/lexikon/index.php/MineralData?mineral=Guilleminite Mineralienatlas] 2. ^Webmineral data 3. ^1 Guilleminite: Guilleminite mineral information and data on Mindat.org 4. ^Pierrot R, Toussaint J, Verbeek T.
