What is Titanite? 

Formerly known as sphene (the Greek word for “wedge”), Titanite is a common mineral in many igneous rocks and in metamorphic rocks such as gneiss and schist. It occurs as translucent or transparent crystals. It is found in numerous locations, and can occur as reddish brown, grey, red, yellow or green monoclinic crystals. In addition to its use as gems, it is also a source of Titanite dioxide, which is used in pigments.
