| One of my favorite gems is sphene, or more properly, titanite. |
| Reddish grains of sphene or of garnet are occasionally visible. |
| Accessory minerals are represented by apatite, zoisite, sphene, calcite, fluorite and magnetite. |
| Ilmenite is now largely preserved as skeletal crystals in which exsolved magnetite lamellae have been altered, and the ilmenite itself partly altered to sphene. |
| Among other minerals found in them are biotite, chlorite, tourmaline, epidote, apatite, garnet, hornblende, augite, sphene and pyrites. |
| How about sphene versus titanite, or celestine versus celestite? |
