Short summary
Ellinaite, a natural analog of β-CaCr2O4, was discovered at Hatrurim Basin, Israel, and in an inclusion within the super-deep diamond from the Sorriso Creek placer, Brazil. Chemical composition, structural data and physical properties are given for this mineral. It is related to multiple oxides AB2O4 with tunnel structure. This group now includes eight minerals. The overview of ellinaite from all localities suggests different PT–X–fO2 conditions for the mineral and its host rocks.
