Kyawthuite is a rare mineral[2] with a simple formula: Bi3+Sb5+O4.[3] It is a natural bismuth antimonate. Kyawthuite is monoclinic, with space group I2/c, and is isostructural with clinocervantite,[2] its trivalent-antimony-analogue.[4] Kyawthuite is also an antimony-analogue of clinobisvanite.[5] Kyawthuite was discovered in the vicinity of Mogok in Myanmar, an area famous for its variety of gemstone minerals.[6] Only one sample of the naturally occurring form of this mineral has been found and is stored at the Natural History Museum of Los Angeles County.[7]
