Sphene is named from the greek word for wedge, because
of its typical wedge shaped crystal habit. It is also
alternatively called titanite for its titanium content.
Spene can be cut as gems although it is considered a
rarity on the gem market. It brings to the table a fire
greater than diamond and unique color shades. However
its softness limits its desirability as a gemstone.
Twinning is common in sphene and forms a classic twin
shape that is found mostly in Pakistan. The twin is
shaped like a deflated, caved-in football, only with
flatter surfaces. Spene can form nice crystals and can
make a lovely addition to the collection of a collector
who appreciates different crystal forms.
