| About the name | Named by Gustav Rose in 1839 in honor of Count Lev Alekseevich Perovski (1792-1856), then in the Ministry of Regions, of St. Petersburg, Russia. Perovskii rose to vice-president of the Appanage Department in 1852-1856. During his tenure in the Appanage Department, Perovski "contributed to the development of mining industry in Russia, inspected supplies and working of lapidary work; many new deposits started to be mined by his initiative." Perovski was also an influential mineral collector. (Schmidt, 2011). |
| Streak | Colourless, greyish white |
| Crystal System | Orthorhombic |
| Cleavage Type | Imperfect/Fair |
| Fracture type | Irregular/Uneven,Sub-Conchoidal |
| Morphology | Crystals usually cubic, highly modified at times, but the planes are often irregularly distributed. Cubic faces striated parallel to [001] and apparently penetrations twins (as if of pyritohedral individuals; also striated parallel to [110]. {001} less developed with {113} and {449} prominent. Also cubooctahedra or octahedra (esp. Ce and Nb varieties). Rarely reniform masses exhibiting small cubes on the surface, or massive granular. |
| Twinning | On {111}: 1. penetration twins (esp. Ce or Nb varieties); 2. complex lamellar twinning. About [101] and rarely [121] |
| Thermal Behaviour | In forceps and on charcoal, infusible. Dissolves easily with salt of phosporous in oxidizing flame, giving a greenish bead while hot, becoming colorless on cooling. |
