Detailed sheet
titanite
Identified in 1795, its name expresses its high content of titanium.
It has long been known as sphene, which came from the Greek “sphenos” for corner, which described very well the shape of its wedge-shaped crystals.
Brookite, of the same composition, crystallizes in another crystal system : orthorhombic and with an even larger dispersion.
Mineralogists call it titanite but the old name of sphene is most used by gemologists.
There is a chromian variety emerald green.
