Sometimes this species is referred to as "Sphene" but it is an outdated name and the correct name is Titanite though both are accepted in the gem and mineral world. It seems to me that more often it is referred to as "Sphene" in the gem world and Titanite is used for crystallized specimens. One of the great aspects of faceted Titanite is the high dispersion of the material. This gem has a deep greenish-golden color, and is a good sized stone for this material. The stone has a Square Emerald cut and is only very slightly included.
