This sphene
displays stunning brilliance. The gemstone features “fire” phenomena
which is a special feature of Sphene. In one direction the gem displays a
canary yellow colour, in the other direction the gem jumps to life with flashes
of green “fire”. This gem is brilliantly cut by a skilled cutter.

Sphene, also
called titanite for its titanium content, is a fairly unusual gemstone that
until a very few years ago was virtually unknown to most jewelry consumers.
Sphene is a rare collector stone with an unusually high refractive index and
and a hardness of 5 -5.5. Because of it’s high dispersion and refractive index,
a well cut sphene can display stunning brilliance.
